The stereotypical chaotic-good [person] is the white knight who refuses to join any group and goes about on his/her own, doing good.
A chaotic good [person] acts as his conscience directs him with little regard for what others expect of him. He is kind and benevolent, a strong individualist hostile to the claims of rules, regulations, and social order. He hates it when people try to intimidate others and tell them what to do. He will actively work to bring down unjust rulers and organizations and to liberate the oppressed. He finds lawful societies distasteful and will avoid them, often living as a nomad or hermit. The best example of a chaotic good [person] is one of the benevolent rogue who steals from the rich and gives to the poor.
Chaotic good combines a good heart with a free spirit.
Took this a while ago but I forgot to post the result. It fits me.
