1. Jasper got a spear through the chest. The CW "Pilot" (Season 1, Episode 1)The pilot of The 100 ended with a bang — or, uh, a spear — when Jasper (Devon Bostick) was nearly killed by Grounders. (He totally died, actually, but that got retconned when the producers realized they liked having Bostick around. But the series quickly stepped away from fake-out deaths!) 2. Clarke mercy-killed Atom with a knife in the throat. The CW "Earth Kills" (Season 1, Episode 3)Atom (Rhys Ward) had been exposed to Acid Fog, so Clarke (Eliza Taylor) was doing him a solid here. Still: yikes. Lots of mercy killing on this show! 3. Charlotte murdered Wells. The CW "Earth Kills" (Season 1, Episode 3)Hey, remember when one of The 100's main characters got killed by a little girl in the third episode? Charlotte (Izabela Vidovic) clearly wasn't in her right mind when she stabbed Wells (Eli Goree) in the neck, but it was seriously upsetting regardless. 4. Murphy got hanged for killing Wells. (And survived.) The CW "Murphy's Law" (Season 1, Episode 4)Yes, Murphy (Richard Harmon) made it through his ordeal and was eventually exiled (and then brutally tortured offscreen). But the hanging scene was still one of the more distressing examples of mob violence in The 100's first season. And he didn't even kill Wells! 5. Charlotte committed suicide. The CW "Murphy's Law" (Season 1, Episode 4)How do you solve a problem like a pint-sized murderer? In this case, Charlotte leapt off a cliff to her doom and avoided an awkward trial scenario. Problem solved! 6. 320 Sky People died from oxygen deprivation in the Culling. The CW "Twilight's Last Gleaming" (Season 1, Episode 5)Hey, they volunteered! Also, it's comforting to know that life on the Ark is about as awful as life on Earth — it's just a different kind of terrible. 7. Grounders killed three Delinquents. The CW "His Sister's Keeper" (Season 1, Episode 6)Don't worry, many more to come! RIP John Mbege (Aaron Miko), Diggs (Giacomo Baessato), and Roma (Celia Reid). We hardly knew ye. 8. Bellamy killed Dax in self-defense. The CW "Day Trip" (Season 1, Episode 8)Yes, Bellamy (Bob Morley) stabbed Dax (Victor Zinck Jr.) in the neck — lots of neck stabbing on this show! — but Dax was about to crush his throat. Amid all the senseless murders on The 100, this one was downright honorable. 9. Commander Shumway was murdered, and it was staged to look like a suicide. The CW "Day Trip" (Season 1, Episode 8)On orders from the treacherous Diana Sydney (Kate Vernon), Lt. Graco (Artine Brown) slit Commander Shumway's (Terry Chen) wrists with a shard of broken glass and staged his body to make it look Shumway had killed himself. Again, life on the Ark: not peachy! 10. An explosion took out six Sky People. The CW "Unity Day" (Season 1, Episode 9)Including four Council members and Vera Kane (Christine Willes), mother of Council member Marcus Kane (Henry Ian Cusick). This was Diana's doing, naturally. 11. The drop ship from the Ark crashed, killing everyone on board. The CW "Unity Day" (Season 1, Episode 9)On the plus side, Diana didn't make it. Unfortunately, Clarke thought her mother Abby (Paige Turco) was on the ship, so witnessing this explosion was actually pretty devastating. But Abby was fine! Yes, a whole lot of Sky People died in the crash, but we never even learned their names. 12. And in the shutdown on the Ark caused by the drop ship, about 1,500 Sky People died. The CW "Unity Day" (Season 1, Episode 9)So there's also that. 13. Murphy smothered Connor. The CW "I Am Become Death" (Season 1, Episode 10)After claiming he was going to let bygones be bygones and forgive Connor (Joshua Ssettuba) for the whole trying-to-hang-him thing, Murphy smothered his former friend to death with a wet rag. And he said "bygones" while doing it. 14. Clarke tried to save a dying Grounder, who died anyway. The CW "The Calm" (Season 1, Episode 11)Turns out, there are consequences to blowing shit up! In this case, Tris (Alison Thornton) was mortally wounded. Anya (Dichen Lachman) forced Clarke to try to save Tris, threatening to kill Finn (Thomas McDonell) if Tris died. Tris didn't make it, but Clarke and Finn were able to escape relatively unscathed. 15. Clarke slit Caliban's throat. The CW "The Calm" (Season 1, Episode 11)Of course, in order to escape and save Finn, Clarke had to slice Caliban's (Steve Bacic) throat with a scalpel. She had no other choice! 16. Murphy suffocated Myles. The CW "We Are Grounders (Part 1)" (Season 1, Episode 12)More revenge, more suffocation. This time, Murphy used a plastic bag to murder Myles (Brendan Meyer). Creative! 17. Reapers literally tore a Grounder apart. The CW "We Are Grounders (Part 1)" (Season 1, Episode 12)This whole scene was a big bloody mess. Reapers slaughtered and ate a Grounder. Lincoln (Ricky Whittle), Finn, and Clarke fought back. Both Reapers and Grounders suffered some serious losses. But really, what you should be focusing on here is that Reapers slaughtered and ate a Grounder. Gross. 18. Murphy shot Raven. The CW "We Are Grounders (Part 1)" (Season 1, Episode 12)Murphy is a real menace, huh? Raven (Lindsey Morgan) survived, but her injuries have continued to haunt her throughout the series. 19. Drew was killed by a Grounder scout. The CW "We Are Grounders (Part 2)" (Season 1, Episode 13)Bonus points if you can remember anything about Drew (Levi Meaden). That having been said, his death was especially gruesome. 20. An Ark station exploded, killing everyone inside. The CW "We Are Grounders (Part 2)" (Season 1, Episode 13)That's not including everyone who died from the Ark ships that crashed en route to Earth. Basically, a very small percentage of Sky People actually managed to make it down to land. At least Abby and Kane ended up safe and accounted for: Soon they'd be able to attempt survival in a new hostile environment! 21. 27 Delinquents were killed in the battle with the Grounders. The CW "We Are Grounders (Part 2)" (Season 1, Episode 13)Rest in peace, nameless teens! (In case you weren't keeping track, it's been a long time since the titular "100" of the title was accurate.) 22. And more than 300 Grounders were killed in the same battle. The CW "We Are Grounders (Part 2)" (Season 1, Episode 13)Mostly incinerated, to be exact, after Jasper blasted the ship's rockets to decimate the Grounders who had assembled outside. A brutal victory for the Delinquents, which, uh, yay? As The 100 repeatedly reminds us, war is fucking awful. 23. Tristan murdered a Delinquent who wasn't moving fast enough. The CW "The 48" (Season 2, Episode 1)Despite Finn's protestations, Tristan (Joseph Gatt) couldn't abide dawdling, so he slit the Delinquent's throat. Rest assured he would soon face his comeuppance. 24. Kane shot Tristan. The CW "The 48" (Season 2, Episode 1)All's well that ends well? 25. Raven was forced to undergo surgery without anesthesia. The CW "Inclement Weather" (Season 2, Episode 2)Raven had Finn by her side to hold her hand and comfort her, but nothing could really prepare anyone for surgery while awake. And although we didn't see much of the actual operation, thankfully, Raven's screams as Abby cut into her were pretty unbearable to hear. 26. Three Sky People were crucified. The CW "Inclement Weather" (Season 2, Episode 2)One was left alive, so points there! This horrific display left a clear message to the Sky People — not to mention people who watch The 100, namely: This show is intense as hell. 27. Clarke discovered that Grounder blood was being harvested. The CW "Inclement Weather" (Season 2, Episode 2)Of course, it only got worse from here, so this seems relatively tame in retrospect. But it was shocking to see Grounders hung upside down, with their blood being circulated through Mountain Men at Mount Weather. It laid the groundwork for increasingly awful human experiments to come. Fun! 28. Abby was whipped in front of a crowd. The CW "Reapercussions" (Season 2, Episode 3)To punish Abby for letting the prisoners escape, Kane had her whipped in front of a crowd. She endured 10 shock lashes at the hands of Major Byrne (Kendall Cross), and while Kane was obviously conflicted about it, it was still awful to watch. (And surely worse to experience!) 29. Finn shot an unarmed Delano. The CW "Reapercussions" (Season 2, Episode 3)After a heated debate about what to do with Delano (Brendon Zub), the Grounder they were questioning, Finn unceremoniously shot him in the head. Finn's murder of an unarmed man foreshadowed some of his subsequent bad decisions, many of which were less than humane. 30. Anya tore out a tracking device from her arm with her teeth. The CW "Many Happy Returns" (Season 2, Episode 4)Look, this was unquestionably badass, but it was also super fucking gross. Kudos to Anya for doing it — now let's never speak of it again. 31. Anya was shot and killed by a Camp Jaha guard. The CW "Many Happy Returns" (Season 2, Episode 4)She and Clarke had finally formed an alliance and were prepared to take on Mount Weather together. Obviously, because this is The 100, that couldn't last. 32. Lincoln was forcibly injected with drugs. The CW "Human Trials" (Season 2, Episode 5)The drug, which made him convulse in agony, was designed to turn him into a Reaper. As a fun side effect, he became dangerously addicted. 33. Finn massacred a group of 18 Grounders. The CW "Human Trials" (Season 2, Episode 5)So, things got a little out of hand and Finn sort of accidentally gunned down a bunch of innocent Grounders. It was not one of his finest moments. Of all the terrible things that have happened on this show, seeing Finn kill so many people en masse was easily one of the most haunting. 34. Lincoln, as a Reaper, killed and ate Sgt. Scott. The CW "Fog of War" (Season 2, Episode 6)The loss of Sgt. Scott (Warren Belle) wasn't exactly deeply felt. But being killed and eaten by Reapers is a shitty way to go — especially when one of the Reapers, much to Octavia's (Marie Avgeropoulos) horror, was Lincoln. 35. Kane sliced open his wrist after Jaha refused to kill him. The CW "Fog of War" (Season 2, Episode 6)Pitted against each other in a fight to the death, neither Kane nor Jaha (Isaiah Washington) could do the deed. But Kane was more than willing to take matters into his own hands and slice open his arm. (He survived.) 36. Keenan was left outside to die from radiation poisoning. The CW "Long Into an Abyss" (Season 2, Episode 7)Cage Wallace (Johnny Whitworth) showed some sympathy and wanted to let Keenan (Emily Haine) back inside, but Dr. Tsing (Rekha Sharma) insisted on leaving her to die as part of her experiment. Science! 37. Dr. Tsing drilled into Harper to steal her bone marrow. The CW "Long Into an Abyss" (Season 2, Episode 7)It might sound strange to talk about stealing bone marrow, but that's exactly what happened to Harper (Chelsey Reist). As she begged to go home, Dr. Tsing drilled into her against her will — and, of course, without anesthesia — to withdraw bone marrow. Dr. Tsing: not a great doctor. 38. Clarke mercy-killed Finn. The CW "Spacewalker" (Season 2, Episode 8)If Clarke hadn't stabbed Finn, he would have been killed by the Grounders — and in a much more horrific way. But this was a major turning point for Clarke, and a deeply upsetting moment. Those final seconds — Clarke's bloody hand, Finn's slumped-over corpse, Raven's scream — are hard to forget. 39. Gustus faced "Death by a Thousand Cuts." The CW "Remember Me" (Season 2, Episode 9)After attempting to poison Lexa (Alycia Debnam-Carey), Gustus (Aleks Paunovic) was punished with the Grounders' "Death by a Thousand Cuts." At least Clarke got to see how awful this execution was: That's the fate Finn would have faced if she hadn't killed him first. 40. Pauna attacked and killed three people. The CW "Survival of the Fittest" (Season 2, Episode 10)Pauna is a giant gorilla, because it's important to remember that there are lots of things on Earth that will kill you other than your fellow humans. Anyway, RIP Major Byrne, Quint (Graham Shiels), and Lexa's guard (Arleo Dordar). Sorry you got mauled. 41. Bellamy strangled Sgt. Lovejoy to death. The CW "Coup de Grâce" (Season 2, Episode 11)To be fair, Bellamy was going through a lot: getting harvested at Mount Weather can't be fun. And Sgt. Lovejoy (Eric Breker) would have killed Finn — and Maya (Eve Harlow) — if Finn hadn't killed him first. 42. Jasper, Monty, Harper, and Miller watched Dr. Tsing die from radiation poisoning. The CW "Rubicon" (Season 2, Episode 12)OK, Dr. Tsing was a horrible person, and she let plenty of people die from radiation poisoning — you know, when she wasn't drilling bone marrow out of them. And Jasper, Monty (Christopher Larkin), Harper, and Miller (Jarod Joseph) had good reasons to hate her. Still, this was pretty brutal. 43. A missile killed more than 250 Grounders and Sky People, and Clarke could have stopped it. The CW "Rubicon" (Season 2, Episode 12)Lexa could have stopped it, too, of course, but she's not our hero and we hold her to a different standard. The point is, Clarke chose the greater good again and that meant letting a whole lot of her people die horrible deaths. Abby's disgust with her daughter was extreme — but this was a hard choice to accept. 44. A Mount Weather sniper shot several Grounders. The CW "Resurrection" (Season 2, Episode 13)The sniper, Whitman (Rob Hayter), did some serious damage before Clarke eventually put him down. What's important, however, is that Indra (Adina Porter) survived her injury. 45. The Delinquents violently fought back against the Mount Weather guards. The CW "Resurrection" (Season 2, Episode 13)To be clear, this was a good thing! But it was also really intense. Seeing Jasper wield an axe with blood spraying the walls was a lot. This whole scene was a mess of stabbing and smashing and bludgeoning. Viva la resistance! 46. Jaha's group wandered into a minefield. The CW "Bodyguard of Lies" (Season 2, Episode 14)And that's why you should always mark your minefields! Jaha and Murphy survived, but they probably had a tough time moving past the image of body parts raining from the sky. 47. Mr. and Mrs. Peters were shot in cold blood for hiding Jasper and Maya. The CW "Blood Must Have Blood (Part 1)" (Season 2, Episode 15)Poor Mr. (Frank Ferrucci) and Mrs. Peters (Crystal Verge) — they were executed for trying to do the right thing. And poor Jasper and Maya, who had to watch these good samaritans murdered even after they'd turned themselves in. Traumatic! 48. Maya found her father dead. The CW "Blood Must Have Blood (Part 1)" (Season 2, Episode 15)It should probably be noted that Maya discovering the corpse of her father, Vincent (Ian Tracey), happened while countless Grounders and Mount Weather guards were killing each other outside. So, you know, quite a brutal episode overall! 49. Fox's corpse was dropped from a chute into a mining cart. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)The indignity of an offscreen death is bad enough, but Fox (Genevieve Buechner) — who'd been around since the beginning — had her dead body dropped thoughtlessly into the mines after she'd been drilled of all her bone marrow. Not a great ending for the character. 50. Raven got shocked and then drilled into. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)Because Raven hadn't suffered enough, apparently? 51. Clarke executed Dante. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)Dante Wallace (Raymond J. Barry) ended up siding with his awful son Cage, but Clarke still didn't really have any reason to kill him. Once it was clear she couldn't use him as a bargaining chip with Cage, she probably should have just let him go. Instead she shot him in cold blood. 52. Clarke and Bellamy irradiated Mount Weather, killing about 350 people. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)Again, this was an example of Clarke doing what she thought she had to do for the survival of her people. And it was probably the right choice! But yikes, was it awful. Let's not forget how many residents of Mount Weather were completely innocent. A lot of these victims were children. 53. Maya died in Jasper's arms. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)Among the innocent: Maya, who spent the entire season doing whatever she could to help the Delinquents, repeatedly putting her own life at risk. And in the end, she died along with a bunch of other people who didn't deserve to, with poor Jasper left holding her corpse. 54. Lincoln cut off Cage's hand, then injected him with the red drug. The CW "Blood Must Have Blood (Part 2)" (Season 2, Episode 16)Given all the awful things Cage did, he kind of got off easy. He never had to adjust to life with one hand because shortly after Lincoln chopped that appendage off, he injected Cage with the same drug that Cage had forced on Lincoln. Cage, however, did not survive. 55. Raven and Miller killed three Ice Nation warriors. The CW "Wanheda (Part 1)" (Season 3, Episode 1)Well, first Jasper antagonized the Ice Nation warriors — and then one of the warriors started to slit Jasper's throat. So, justified, but still unfortunate. 56. Emori stabbed Gideon in the neck. The CW "Wanheda (Part 2)" (Season 3, Episode 2)This was only after Murphy had hit Gideon (John DeSantis) several times in the head, to no avail. Gideon seemed surprised by Emori's (Luisa D'Oliveira) quick throat slash — and viewers were certainly shocked by the impressive amount of blood that ensued. 57. Lexa kicked an Ice Nation representative out a window. The CW "Ye Who Enter Here" (Season 3, Episode 3)(This was way more awesome than brutal, but like, yeah, violence is bad.) 58. Gina was stabbed by an Ice Nation assassin. The CW "Ye Who Enter Here" (Season 3, Episode 3)We barely got a chance to know Gina (Leah Gibson) before she ended up on the wrong end of an assassin's knife. Still, she fought valiantly until the end! And she and Bellamy seemed to have a nice (albeit sadly truncated) relationship. RIP Gina. 59. Mount Weather exploded, killing everyone inside. The CW "Ye Who Enter Here" (Season 3, Episode 3)That would be the 35 Sky People from Farm Station who were being housed here. Honestly, given all the terrible things that have happened at Mount Weather, it's probably for the best that it's gone for good. But a lot of innocent people, again including children, died in the blast. 60. Lexa threw a spear through Queen Nia's heart. The CW "Watch the Thrones" (Season 3, Episode 4)Well, that was unexpected. Although Queen Nia (Brenda Strong), leader of the Ice Nation, was set up to be a major adversary, Lexa spared Nia's son Roan (Zach McGowan) and instead threw her spear at Nia, killing her. Now let's all just breathe a sigh of relief that Lexa survived.
