Blog 3# - Moral Pyromaniac?

"Iago, as Harold Goddard finely remarked, is always at war; he is a moral pyromaniac setting fire to all of reality.......In Iago, what was the religion of war, when he worshiped Othello as its god, has now become the game of war, to be played everywhere except upon the battlefield."
--Harold Bloom

To respond to this passage, one should mostly focus on the shift from a religion to a game. How would you prove that this insightful comment is true? Of course, in order to prove this idea is true, do not fail to incorporate the excellent idea of "a moral pyromaniac" in this shift.
