Is there any capeshit hero character that just doesn't give supervillains a chance to go down a path of villainy? Where he just fucking kills them the first chance he gets? Doesn't attempt to redeem them, get to become familiar with them or even give a shit if they had a sad backstory. Just fucking kills you for even attempting to start shit.
The only character that comes close to ever do this is the punisher be he only ever deals with regular human criminals. Not some one who suddenly got bullshit powers out of nowhere and the first thing they do is immediately become a professional criminal.
