Being lawful is about how much you trust and value what other people think. Forget the actual law, that's what it's really about. It's about holding yourself to the standards of other people and acknowledging that you are responsible for meeting their expectations when interacting with them. Chaotic is about valuing your own standards above all else, even if you're acting on behalf of someone else. A Lawful Good person is empathetic, a Lawful Evil one is manipulative. Both are paying attention to what other people want and expect of them.
