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 beings believe their alignment is the best because it combines self-interest and pure freedom.
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.
The major precepts of this alignment are freedom, randomness, and woe. Laws and order, kindness, and good deeds are disdained. Life has no value. By promoting chaos and evil, those of this alignment hope to bring themselves to positions of power, glory, and prestige in a system ruled by individual caprice and their own whim. The chaotic evil creature holds that individual freedom and choice is important, and that other individuals and their freedoms are unimportant if they cannot be held by the individuals through their own strength and merit. Thus, law and order rends to promote not individuals but groups, and groups suppress individual volition and success.
