Nope. I'm done. This is stupid, nonsensical edgelord garbage starring a shit protagonist.
Really, this feels like the kind of thing a chuuni kid would come up with. Even the fact that it's kind of gory but not really plays into that. It's like a 12-year-old's idea of a "mature" story because the MC had a crap life and doesn't understand these human emotions while his true potential is buried inside him. The only thing missing is him doing that stupid "claw hand over the face, looking through his splayed fingers" gesture that shit manga loves so much.
