Rape, murder, cancer, and other bad things are evil because they distort the way the world should be. Sex should be an act of love, not an act of violence. Cells should grow into body parts, not tumors. If evil refers to the way things are not supposed to be, then good must refer to the way things are supposed to be. But if things are supposed to be a certain way, then that means there is both a cosmic plan and a cosmic planner—a planner that many people call God.
