I'm Neutral Good AND Chaotic Good, and where the coin ultimately falls depends on my circumstances.
I have a strong moral code that is completely defined by my spiritual beliefs, and not by society or the law. Whether or not I feel any sort of guilt or remorse for my actions is a question of whether or not I have disobeyed my personal moral code. While I may fear for the consequences of illegal or other rule-breaking actions, I feel no remorse for "breaking the rules" unless a certain action that "breaks the rules" also violates my moral code (that's the Chaotic Good part).
At the same time, I understand that the law, and rules in general, have its place in society. I understand that following the law/rules upholds order at home, the workplace, and society in general, and I don't want to live in a chaotic society. Therefore, I will not flippantly disregard the law/rules, but I don't wholeheartedly embrace them as the moral standard for everyone either (that's the Neutral Good part).
In the end however, if push comes to shove and I am forced to choose between obeying my personal moral code and obeying the civil code, I will choose my personal moral code in heartbeat and not feel bad about it for a second.
In short... In my everyday demeanor and practice, I'm Neutral Good. But in my heart of hearts, I'm Chaotic Good.
