It might be interesting to look at this from the perspective of an evil character, they might be aware that they are Evil, but to them that word might have another connotation, to them it means Strong. They have the strength to make the hard calls, the dirty choices, they get the job done.
Another aspect is that people tend to be amazingly good at convincing themselves that everyone is just like them, whether they admit it or not. They might see Good folks wandering around doing whatever it is they do, as simply being too weak to really take what they really desire or face the consequences. Good just means you've tricked yourself into acting against your own best interests.
Of course, as has been mentioned up-thread, these sorts of philosophical have been plaguing the world for uncountable years. It's entirely possible we won't ever settle on the answer, because there isn't really one answer.
