There is "common", animalistic evil such as lust, anger, greed, gluttony, etc.
There is also more "refined" evil such as deception, the desire to control another, the desire to hurt someone deeply without cause, etc. A type of pleasure seems to be experienced in people who engage in this type of evil beyond simple animal gratification.
How do the latter forms of evil arise out of the former?
Is it a result of the complexity and strength of certain egos within the individual?
In the end, are even the most refined types of evil just the product of lust?
