Nothing [the demon] could think up was half as bad as the stuff [people] thought up themselves. They seemed to have a talent for it. It was built into their design somehow. They were born into a world that was against them in a thousand little ways, and then devoted most of their energies to making it worse.
The truth is, it's not the idea, it's never the idea, it's always what you do with it.
