Run around dressed as a bat beating people to a vegetative state

Batman's no kill policy is definitely not for any kind of moral objection to taking lives, that's for sure. He brutalizes normal ass people with extreme excessive force on the regular. There's no chance that none of these people succumb to their injuries soon after. It's probably just to make himself feel better about it, a cope that allows him to justify it all by saying he didn't necessarily inflict mortal wounds on purpose.
