"People who couldn’t imagine themselves capable of evil were at a major disadvantage in dealing with people who didn’t need to imagine, because they already were. Lowbeer had said it was always a mistake, to believe those people were different, special, infected with something that was inhuman, subhuman, fundamentally other. Which had reminded Flynne of what her mother had said…That evil wasn’t glamorous, but just the result of ordinary half-assed badness, high school badness, given enough room to become its bigger self, with more horrible results."
