“Hell needed horribly bright, self-centered people like Eric. They were much better at being nasty than demons could ever manage”

“The fact was that, as droves of demon kings had noticed, there was a limit to what you could do to a soul with, e.g., red-hot tweezers, because even fairly evil and corrupt souls were bright enough to realize that since they didn't have the concomitant body and nerve endings attached to them there was no real reason, other than force of habit, why they should suffer excruciating agony. So they didn't. Demons went on doing it anyway, because numb and mindless stupidity is part of what being a demon is all about, but since no one was suffering they didn't enjoy it much either and the whole thing was pointless. Centuries and centuries of pointlessness.”

“Mere animals couldn’t possibly manage to act like this. You need to be a human being to be really stupid.”

“But the point about that kind of stuff was that you needed someone around to be proudly independent and self-reliant. People who didn’t need people needed people around to know that they were the kind of people who didn’t need people.”

“Any wizard bright enough to survive for five minutes was also bright enough to realize that if there was any power in demonology, then it lay with the demons. Using it for your own purposes would be like trying to beat mice to death with a rattlesnake.”

“There were people who called themselves Satanists who made Crowley squirm. It wasn't just the things they did, it was the way they blamed it all on Hell. They'd come up with some stomach-churning idea that no demon could have thought of in a thousand years, some dark and mindless unpleasantness that only a fully-functioning human brain could conceive, then shout "The Devil Made Me Do It" and get the sympathy of the court when the whole point was that the Devil hardly ever made anyone do anything. He didn't have to. That was what some humans found hard to understand. Hell wasn't a major reservoir of evil, any more than Heaven, in Crowley's opinion, was a fountain of goodness; they were just sides in the great cosmic chess game. Where you found the real McCoy, the real grace and the real heart-stopping evil, was right inside the human mind.”

“...and the funny thing was that people who weren't entirely certain they were right always argued much louder than other people, as if the main person they were trying to convince were themselves.”
