A chaotic neutral character follows his whims. He is an individualist first and last. He values his own liberty but doesn't strive to protect others' freedom. He avoids authority, resents restrictions, and challenges traditions. A chaotic neutral character does not intentionally disrupt organizations as part of a campaign of anarchy. To do so, he would have to be motivated either by good (and a desire to liberate others) or evil (and a desire to make those others suffer). a chaotic neutral character may be unpredictable, but his behavior is not totally random. He is not as likely to jump off a bridge as he is to cross it.
Chaotic neutral represents freedom from both society's restrictions and a do-gooder's zeal.
For me it is always this one. It provides the freedom for my characters to do whatever they d@mn well please, without regard to anyone's rules or laws. If one moment I feel like rescuing the damsel in distress, and the next moment I actually shoot her myself, it doesn't matter. That kind of ethical freedom is liberating to be able to play with, and also, much as yourself Burma, not something I would ever be okay with IRL.
