I recently understood this from a Christian Perspective.
It took a long time for me to comprehend how a person calling themselves a Christian would say that it's not Evil for a Pharmaceutical company to overcharge for a drug that people's lives depend on. The idea was mind boggling to me. But then it hit me. They believe that the Pharmaceutical company may do what they want with their property because it's their property, much like they believe that God may do with his property what he wants to because it's his property. God can flood the world if he likes, because it's his property, we (according to them) belong to him. So there is nothing he can do to us that is 'immoral'. Satan on the other hand wants God's property for himself. Therefore he is evil (in their system of morality).
