From Randy Gauger's Blog:
"I picked up my old copy of C. S. Lewis' The Screwtape Letters. I had read it nearly 20 years ago. I discovered that it grabbed my attention again. It reminded me once more how subtle evil can be.
Lewis suggests that evil is not done in concentration camps. Such atrocities are the results of evil (page x). After evil has become full grown, the horror of concentration camps emerge. But where does evil begin. Lewis writes: "We must picture Hell as a state where everyone is perpetually concerned about their own dignity and advancement, where everyone has a grievance, and where everyone lives the deadly serious passions of envy, self-importance, and resentment" (page ix)."
