Chaotic good combines a good heart with a free spirit. In 4th edition mechanics for Dungeons & Dragons chaotic good is found under the umbrella of the good alignment.
A chaotic good character 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.
James Bond is a good example of Chaotic good
