Evil is not a theory.
It’s not a concept created by angry, red-face preachers trying to stop people from having a good time.
Evil is what flies airplanes into buildings and drives an automobile into pedestrians.
But evil doesn’t happen in a vacuum. No one wakes up one morning, in the middle of a fine, stable, happy life and decides, “I’m going ram my car through a crowd of people today.”
We get to places like that slowly. Piece by piece. Step by hateful step.
