Would you consider the xenomorphs from the Alien franchise as creatures that consider themselves evil, [@MelonHead]? They're always chaotic evil.

For the more interactive characters of that alignment, the less complex excuses used will typically "its fun" or "I can" or "its necessary". Just because everyone else considers their acts to be evil, rarely means that they themselves do. Many chaotic evil characters are incapable of restraint for some reason or other. When you're incapable of that, you generally can't decide whether you're good or evil.
For far better explanation and examples, we send you [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/ChaoticEvil]here[/url].

We'd suggest going with a fairly standardized plot,[@Blackmist16]. Maybe a small twist or two to make it unique, but make the essence what others have done before.

Heh, Xenomorphs are a bad example because they are definitely not Chaotic Evil, everything they do is based around their drive to see their species survive and so they must acquire hosts to propagate themselves. They would probably be neutral in terms of alignment.

I'm not saying I disagree with your view that 'evil' characters are usually labelled as such by the good guys as a result of their differing ideologies, but I think there are definitely some exceptions to this, certain archetypes which are fully aware that they are evil and their actions are morally reprehensible. Demons for example, which just don't give a shit that they're doing terrible things, and Vampires sometimes as I mentioned.

I suppose the only evil characters which are aware they are evil are characters capable of having doubts about their actions, or have a sense of morality that they are breaking for some reason (like Vampires)
