I agree completely. The DO won't stop at Equality - with the Snarl under his thumb, he will head all the way to Supremacy. Remember that he used to be a warlord before achieving divine status, and that he has armies marshalled in goblin heaven already. He is preparing for all-out divine war, and is simply waiting for his prophet to deliver his secret weapon before he launches the opening salvo.
What LE deity would ever settle for mere coexistence?
