I don't know man. I kinda dislike how goody twoshoes and ineffective the MC is. lIke you are stopping the guy from killing a vat grown rape and murder machine.
Yeah, for his own good. Because beating something to death is not a pleasant or healthy thing to do in most cases. Dude is a civilian who had completely forgone fighting to have a peaceful life with his wife, better for him to return to that life with clean hands rather than kill and go back to being a delinquent or continue being a vigilante.
