What do I gain from the end of the world? I like creation. So much to play with, so much to experience..
And this world - I can't feel Him, can't feel hell, I could probably destroy it but then what - be stuck here in a void with no means of getting back? No, no, no plans for an apocalypse. You can't play with your toys if you break.
Besides, if anyone's going to start a war, it's going to be Amenadiel.
