Chaotic Neutral I always saw as the 'supporting their own needs while not really holding any direction at good or evil'. Sure they will do stuff for their own good that might hurt others, but they aren't going full out killing people or trying to go about in causing harm to others. Really chaotic just usually means what they do isn't always going to be right in the eyes of others, and can be considered in sorts 'random' I guess, at least if your looking at it from societies standpoint. The type that make up their own rules about things.
