Half-assing shit is annoying as fuck. You either kill them and sit in jail for the rest of your meaningless life or just wallow in your own self-pity. Don't do both dude.
I feel like a lot of authors fall into this trap of making the antagonists so evil that it just becomes hilarious and unbelievable. Also that Deus Ex Machina Rapist just so MC could show off his power. I think this one goes in the trash.
at least its not a boring "aaaaa i must have my reveeeenge no matter what !" classic story where the character doesnt even bother to check if the ppl have reformed, at least he knows that they havent now lol
