When one tries to picture the mind that plans it, one quickly comes to a dead end. Even if I had been raised with no moral laws at all, even if there were no cops and no prisons, I’m pretty sure that I still wouldn’t want to spend a crisp Friday morning shooting cowering children. Trying to climb this mountain of wickedness is like trying to climb a glass wall with your bare hands. What happened there is pure evil, and evil, unlike common badness, gives an ordinary mind no foothold.
