Evil
Lawful Evil - A lawful evil villain methodically takes what he wants within the limits of his code of conduct without regard for whom it hurts. He cares about tradition, loyalty, and order but not about freedom, dignity, or life. He plays by the rules but without mercy or compassion. He is comfortable in a hierarchy and would like to rule, but is willing to serve. He condemns others not according to their actions but according to race, religion, homeland, or social rank. He is loath to break laws or promises.
Neutral Evil - A neutral evil villain does whatever she can get away with. She is out for herself, pure and simple. She sheds no tears for those she kills, whether for profit, sport, or convenience. She has no love of order and holds no illusion that following laws, traditions, or codes would make her any better or more noble. On the other hand, she doesn't have the restless nature or love of conflict that a chaotic evil villain has.
Chaotic Evil - These characters are the bane of all that is good and organized. Chaotic evil characters are motivated by the desire for personal gain and pleasure and does whatever his greed, hatred, and lust for destruction drive him to do. He is hot-tempered, vicious, arbitrarily violent, and unpredictable. They see absolutely nothing wrong with taking whatever they want by whatever means possible. Laws and governments are the tools of weaklings unable to fend for themselves. The strong have the right to take what they want, and the weak are there to be exploited. Bloodthirsty buccaneers and monsters of low intelligence are fine examples of chaotic evil personalities. If he is simply out for whatever he can get, he is ruthless and brutal. Otherwise if he is committed to the spread of evil and chaos, he is even worse.
