I would have liked to be a neutral jedi... Although, it seems, everyone has choices. I doubt Revan, when faced with the dilemma of saving or conquering the galaxy, would have opted to go home for some tea and crumpets.
Something I'd like to see, and this is probably a little off topic, is the force actually affecting your alignment. My KoToR jedi has LS mastery... But is using the Kill power - A vile use of the force, so we are told. Why does he remain LS? Surely the use of such a vile power would bring him towards the dark side?
