This is Antoine Leiris, a Parisian whose wife was killed at the Bataclan concert hall on Friday night.
Hélène Muyal-Leiris was a makeup artist who grew up in Paris, according to the Libération newspaper. She had a 1-year-old son with Antoine.
On Monday, Antoine shared a heartbreaking message on Facebook in which he said the Paris attackers would never make him afraid.
Antoine began the message simply, stating that he would never give the attackers "the satisfaction" of his hatred.
You won't have my hate.
On Friday night you stole the life of an exceptional person, the love of my life, the mother of my son but you will not have my hatred. I don't know who you are neither do I want to know, you have dead souls. If the God that you blindingly killed for made us in his image, each bullet in the body of my wife would be an injury in His heart.
So no, I won't give you the satisfaction of hating you. You want it, but to respond to hatred with anger would be to give in to the same ignorance that made you what you are.
He also cited a phrase that pops up in French video games when a user dies. "Perdu. Même joueur joue encore."
You want me to be afraid, to see my fellow citizens with distrust, to sacrifice my liberty for security. Game over. Try again.
Antoine concluded that although he couldn't hide his grief, he would ensure that his son would grow up "happy and free. Because no, you won't have his hatred either."
I saw her this morning. Finally, after a few days and nights of waiting. She was as beautiful as when she went out on Friday night, as beautiful as when I fell head-over-hells in love more than 12 years ago. Of course I am devastated by grief, I'll concede this small victory, but it will be short. I know that she'll join us each day and we'll find each other in the paradise of free souls where you will never have access.
We are two, my son and I, but we are stronger than all the armies of the world. I don't have anymore time to give you, I have to go back to Melvil who's waking up from his nap. He's barely 17 months old, he'll eat his snack as usual and then we'll play like every day and all his life this little boy will have the nerve to be being happy and free. Because no, you won't have his hatred either.
Antoine's post has been shared more than 70,000 times so far and he has received an outpouring of messages of love and support for his strength and courage in the face of what happened.
Fanny Lechevestrier commented under his post: "We can help you win this victory."
