We are compelled by the theory of God's already achieved perfection to make Him a devil as well as a god, because of the existenceof evil. The god of love, if omnipotent and omniscient, must be the god of cancer and epilepsy as well.... Whoever admits that anything living is evil must either believe that God is malignantly capable of creating evil, or else believe that God has made many mistakes in His attempts to make a perfect being.
George Bernard Shaw
