Heroes and Anti-Heroes take different journeys. A hero starts out good, but has to learn to be effective. An anti-hero begins as competent, but needs to learn to use those powers for good.

My favorite example: Luke Skywalker starts out idealistic but clueless. He learns better and becomes a Jedi. Han Solo is competent (shooting first) but cares only for himself and Chewie. He’s inspired to join the cause of the Rebellion.

Different journeys to same place.

There’s other definitions of “anti-hero” floating around. Some use it to refer to a villain protagonist. But I prefer my anti-heroes on the side of Good.
