Fear.

“This is the kind of case that makes you want to believe in true evil, to believe that only someone who’s honest to God evil could do something like that. But that’s not how it is, is it? He’s not evil, being evil would make him special but there’s nothing special about him, he’s just pathetic. Pathetic and all too human. And you know that’s the worst part. He’s not so different from anybody else really, just one more fucked up soul in a world going to shit. I guess that’s what scares me most, he’s just like any of us, so maybe any of us could be just like him.”
