Have fun creating your own ideas of right and wrong (religion can help) and apply them liberally in your character's life. Things can be quirky and unique when filtered through the lens of an altered morality or perspective.

Try to avoid insanity. Sure, a casual observer might consider your actions nonsensical or illogical, but that is because they do not grasp the underlying logic or pattern which dictates your thinking. You are each operating on different assumptions.

E.G: "Truth is subjective. People who project or enforce their truth upon others engage in intellectual slavery." Befriend skeptics, condemn ideologues. Preaching is evil. Sowing widespread doubt is the pinnacle of good deeds.
