An adversary is not one who does loathsome acts for their own sake. He always has a reason that to him is justification. My cat eats mice. Does that make him bad? I don't think so, and the cat doesn't think so, but I would bet the mice have a different opinion. Every murderer thinks the victim needed killing.
We can spend our lives letting the world tell us who we are. Sane or insane. Saints or sex addicts. Heroes or victims. Letting history tell us how good or bad we are. Letting our past decide our future. Or we can decide for ourselves. And maybe it’s our job to invent something better.
