Yeah but when you’re arguing with your conservative parents and you happen to have been dealt the “for the children” card, you play that one at every opportunity. I’ve had much more luck with the argument that punishing people they view as morally inferior often results in harming innocents which is absolutely true and the reason punitive justice is (imo) morally wrong. It’s the same reason I don’t believe in the death penalty; if you find out a guy is completely innocent of some terrible crime he’s in the middle of serving a life sentence for, you can give him his missing salary and let him go, but you can’t bring him back to life.
