The Toleration of Evil
It is impossible for the ordinary human mind to fully grasp the evil of Joseph Stalin. He purposefully engineered the starving to death of over ten million people in Ukraine. In terms of mass murder, Stalin's Ukrainian Holocaust was an even greater crime than Hitler's Jewish Holocaust.
Millions more were hauled off to be enslaved and die in the Gulag, or tortured and shot for the slightest suspicion of anything Stalin was suspicious of. Many of his closest deputies were ordered to put their parents, wives, or children to death to prove their loyalty.
Yet this tyranny, this monstrous evil, is not a mystery. Evil exists, deeply embedded in certain human souls. That isn't mysterious; it is a basic fact of human society. The true mystery is why and how such is evil is tolerated. Stalin tyrannized the Soviet Union for thirty years. In all those years, there is not one single known attempt on his life. Not one.
Which then, is the greater depravity: Stalin killing people, or no one killing him? The former, of course. Evil itself is the greater evil -- but toleration of it is the greater mystery.
