Free Will Defense: Response to the problem of evil arguing that God may be justified in allowing evil because the possibility of evil is logically inherent in free will. If free will is a great good that makes possible other great goods, then these goods might provide sufficient reason for God allowing evil. Since not even omnipotence can do what is logically impossible, God must accept the possibility of evil if he wishes to give some of his creatures free will.1
