The 100 has caused controversy in recent weeks with the deaths of two beloved characters.
The death of Lincoln (Ricky Whittle) in the most recent episode was less of a shock due to hints Whittle had dropped on his own Twitter, as well as tweets from his mother that claimed Whittle had "walked away" due to bullying on set.
In an interview with AfterBuzz TV on Tuesday, Whittle elaborated on his decision to leave the show.
Whittle said he had been in a "very dark place", claiming Rothenberg "chose to belittle me and neglect my character and myself."
He said that the "incredible cast" stuck by him and helped him through a tough time.
Whittle urged fans not to abandon the show or attack people involved on social media.
He also had a positive message for anyone experiencing bullying.

In a statement provided to BuzzFeed, Rothenberg wrote, "Ricky Whittle is a talented actor; I appreciate his work on The 100 and wish him all the best moving forward on American Gods."
