You're not quite evil enough. You're semi-evil. You're quasi-evil. You're the margarine of evil. You're the Diet Coke of evil, just one calorie, not evil enough.

Our reading
An editorial interpretation.
Dr. Evil insults someone by calling them a weaker version of evil. Comparisons with margarine and diet soda turn menace into a joke about substitutes. The repeated put-downs make being insufficiently wicked sound like a serious failure.
