look at the Oracle's speech in the Vish assassination; he starts listing: evil and light, light and darkness, etc., and you have "Paradise or Hell" in your signature, although I know that "or" translates to "or," but then it would be too obvious... although the clue isn't that difficult anyway, because the game is nearing its end.
P.S. I still think he flies away... he cuts off the head of the sinner and takes it with him.
