I know I don't normally agree with you on Azazel's power and rank, but Cain may have been alive as a human first, but turned into a demon later than Azazel. Which is why I only said 'potentially'.

Training Knights of Hell doesn't seem unimportant. If you are training hell's elite assassins and hitmen, chances are, you are one (or the most powerful one) yourself.
