Another way of thinking about it is that if Folian's 'pack' is modeled after a wolf pack, there is a degree of chaos inherent. In a wolf pack the strongest (the Alpha's) lead. However, if the alpha were to sicken, even for just a short time, it is conceivable that another might challenge and/or kill the Alpha, taking it's place and causing a sudden shift in the politics of the pack, as it were. In wolf packs, even below the Alpha level, there is a degree of in-fighting (certainly not often to the death, but rather to establish lines of dominance) between pack-mates to determine the pecking order. You could say that this bit of chaotic anarchy is what builds the lawful order of the pack, together bringing a neutrality along the lawful/chaotic axis of the pack behavior as a whole.
Now to examine the good/evil axis you could look at the individual behavior of a typical pack-member. It balances to neutral because a pack member instinctively realizes or thinks along these lines, "I want to be as tough as I can be because I want to be the Alpha and have the privileges that entails (a greedy and thus 'evil' mindset). Yet, I do not wish so much to harm others in the pack because I know our food, and thus my own food, comes from our ability to work as a team (that's not to say that given the opportunity I won't snatch a bit more meat when I can get away with it). Knowing much of my own health and well-being comes from the overall health and well-being of the pack, I'll do my best to protect the others from outside threats and enusre that the pack as a whole stays strong (more of a 'good' mindset in that the individual sacrifices of themselves for the others in their society)."
So there you can see that as an individual a pack-member has both selfish (evil) and selfless (good) qualities, to overall balance out to a more neutral position along the good/evil axis of character alignment.
Just my own analytical two True worth here.
