There are no wrong answers, only your opinions 🙂
Personally, I think an anti-hero is a bad guy that does good things. He might cheat on his wife, steal, gamble, etc, but when it “matters,” he ends up on the side of what’s good.
Han Solo is an example that comes to mind.
It’s like the saying, “is it wrong because it’s illegal, or is it illegal because it’s wrong?” It’s a recognition that the law doesn’t perfectly overlap what’s morally correct.
Anti-heroes live in that ‘moral-but-not-legal’ area. Contrast that with people who bend the written law to serve immoral ends. Fascists tend to be Lawful Evil.
