“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 … 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.”
– Neil Gaiman and Terry Pratchett, Good Omens
