My ex acts innocent while he r@ped me

Thankfully me and my ex have been broken up for 2 years now, and it ended really badly. He threatened me, blackmailed me, leaked nudes and assaulted me. However, to this day he posts shit like ‘how i feel chilling while the world is full of evil bitches’ and ‘all women are evil and i’m just a chill dude’. It enrages me, he’s genuinely insane and I hope he burns in hell. It’s not fair at all, I can’t sleep because I have nightmares from what he did to me, while he acts all innocent. I wish he wasn’t able to live.
