I agree with the good vs evil thing.  The world is shades of gray, and THAT is what the evil bastards hide in to do evil.  I have encountered true, pure evil in the real world, so I know it DOES exist.  There ARE people who make the choice to get off on the pain of others, to make themselves rise over overs by piling up bodies of people the murdered.  It's like a drug.  They cause pain and death out of a rush or high they get from hurting others to prove they are better than others.

There are people who get feelings of helping others,too.  There you have it. Good and evil.  They do exist and if writers can't at least acknowledge that do really exist, their writing becomes weak and ineffectual.  That means bad stories.

An anti-hero is a hero, just flying in the face of custom or convention, that challenges the status quo to do good in they own style. Hollywood and others forgot that.  Hollywood forgot a LOT of writing techniques.

I cannot save the world. Only my little piece of it. If we all act together, we can save the world.--Nelson Mandela
