I don’t care what I have to do to get what I want.
Chaotic evil characters have a complete disregard for others. Each believes he or she is the only being that matters and kills, steals, and betrays others to gain power. Their word is meaningless and their actions destructive. Their worldviews can be so warped that they destroy anything and anyone that doesn’t directly contribute to their interests.
By the standards of good and lawful good people, chaotic evil is as abhorrent as evil, perhaps even more so. Chaotic evil monsters such as demons and orcs are at least as much of a threat to civilization and general well-being as evil monsters are. An evil creature and a chaotic evil creature are both opposed to good, but they don’t have much respect for each other either and rarely cooperate toward common goals.
