I think that Americana is steeped in good vs evil. Try reading some Manga. They have no absolutes really, and aren't afraid of killing off their main characters (for good) lol,

Hellsing is great, Ororin,

For superheroes I like the Green Arrow, yeah good/evil but at least he has great dialogue, (Kurt Swann, Kevin Smith).

Age of Apocolypse was fun, great colors.

But besides Comic Novels, there are Graphic Novels:

Seth

Transmetropolitan

Lost Girls

The Preacher

Sandman

All are thought provoking.
