Hmm. Back in my D&D days, I always thought that alignments were plain dumb anyways, but seemed a part of the game that just couldn't be excised. My original thought though, was that Rorschach would be Lawful Good, if anything, because of his never compromising. I admit he didn't turn in villains for legal processing, but he would see the "LAW"-ful authorities as being weak and corrupt.
