A chaotic evil character does whatever his greed, hatred, and lust for
destruction drive him to do. He is hot-tempered, vicious, arbitrarily violent,
and unpredictable. If he is simply out for whatever he can get, he is ruthless
and brutal. If he is committed to the spread of evil and chaos, he is even
worse. Thankfully, his plans are haphazard, and any groups he joins or forms
are poorly organized. Typically, chaotic evil people can be made to work
together only by force, and their leader lasts only as long as he can thwart
attempts to topple or assassinate him.
Chaotic evil is sometimes called "demonic" because demons are the epitome of
chaotic evil.
Chaotic evil is the most dangerous alignment because it represents the
destruction not only of beauty and life but also of the order on which beauty
and life depend.
