I'm not quite sure, I guess I would be chaotic good, due to my unpredictability, since I'm never sure to how I'll react to a situation, sometimes I just help people, but sometimes I go ahead and punch people even picking fights with drug dealers and such, just because I'm in a foul mood and those scumbags piss me off, not to mention I hate the government, but I like the law, though I wouldn't hate the government if they actually bothered enforcing the law, also rather annoying that they don't even attempt to look decent, anyway chaotic good because I do most things with good intentions, but I also used to steal stuff from pretty much everybody, not to mention there's always the chance that I'll start punching random people for no apparent reason, so yeah chaotic good seems most appropriate.
Not to mention chaotic good is where super-heroes tend to be placed, and considering how I act, react and think, it's fair to assume that if I actually was good at fighting it wouldn't be unlikely for me to go out at night looking for trouble, specially considering I have already done that though I didn't find any.
