They have tables defining evil actions, e.g. "Left in the desert begging for his life."
And they have others defining evil intent, e.g. "We figured that the best time to put the nerve gas on the train was at rush hour."
With a bonus for evil behavior, e.g. "I didn't rape her, she wanted it."
Plus you can take their survey, to help them figure out how depraved we all are.
I for one think evil should be measured on the Scoville Scale:
That way we could equate some criminals with the Guatemalan Insanity Peppers of Quetzalzacatenango. ¡Ay ay ay!
