Of course! And if you've ever done an Evil thing, it will come back to haunt you every few issues, and will eventually become your defining characteristic. When you die, your tombstone will read, "Here lies That Person Who Was Evil on Occasion but s/he tried, i guess" and your friends will forever remember you for doing some good, or something, and that one evil incident in Prague.
But mostly, Evil is impossible to wash off clothes. It's worse than blood.
But on the other hand, if you're the son of Bruce Wayne, you're automatically -- okay, no, I'm going to stop right here.
