[T]hose who govern us at the present time reject a central insight of Western religion, which is found also in Greek tragic drama and the work of the Roman historians: destructive human conflict is rooted in flaws within human beings themselves.

The restraints of morality exist to curb this innate human frailty; but morality is a fragile artifice that regularly breaks down. Dealing with evil requires an acceptance that it never goes away.
