Chaotic Good, so much so that it's impossible to describe my characters as anything else.
One Idea I had bouncing around my head is a character that goes around defeating all the gods because "Gods are tyrants if they have any influence over the beings of the material plane." Regardless of the alignment of the gods in question.
There was also a similar idea where a character decides to disrupt the "balance" of the 9 Alignments because the way the alignments are set up are almost deliberately set up to cause discord, and sees the nine alignments as false. So he goes around slaying all the gods to set up a new alignment system where it's not good/evil and Lawful/Chaotic, but something else. What the replacements are tend to vary when I'm thinking about it, but most often tends to be either something "elements of harmony based" or "Idealistic/Cynical, Analytical/Emotional".
As for my opinions of real life morality. It's more or less that we are all both good and evil to varying degrees, it's just one is more prominent at certain times. The majority of people lean towards good, but will do what is necessary to survive if threatened (ever been overly defensive when someone sneaks up on you?). And conversely, most people who commit crimes can reasonably be expected to want to turn their life around when threatened with severe punishment.
... but then again, I might be a bit too idealistic for my own good.
