Terry Pratchett, Neil Gaiman. Good signs (№ 372664)

Of course, Crowley has supported the idea of Armageddon - generally speaking. If you would have asked him why he was here so many centuries and in a slipshod manner, interfered in the Affairs of man, he would say, "Well, of course, to bring Armageddon and the victory of Hell." But one thing - to prepare the Armageddon, and quite another to see that he's really going to happen.
Crowley always knew that is not going anywhere, when will the world end because he was immortal, and no choice he had. But he still hoped that before the end of the world is still far away.
Because he liked to order people. And this is a big disadvantage for a demon.
