People imagine the world to be black and white. If someone does something that is deemed evil then they must be an evil person and there can't be any underlying reason that drove them to do this thing.

Take the case of some government workers who turn to the "dark side". I imagine at some point, after earnestly trying to help the American people, these workers get tired of laboring in thankless jobs where they're up against monstrous bureaucracies and just want to do something that benefits themselves and their families. Sadly, and in part because our society rarely rewards beneficial work the way it does exploitation, these people find the path of least resistance to be this sort of journey.

But it seems this kind of second level thinking is impossible for most. We take comfort in fantasizing about a black and white world and condemn others without trying to understand what drove them to act this way. If we could understand the underlying causes maybe we could remove them and prevent as much evil from arising in the future. But we first have to admit that cause and effect are real and apply to human behavior.
