Is it evil for God to cause a sinner to rape another sinner?

The Arminian says that Calvinist teach that God is evil because he causes a woman or a child to be raped by a perpetrator. Of course this is nothing but an emotional argument that seeks not the truth of the matter. The question is what is rape compared to other acts of God revealed in the Scripture alone? God destroys the whole earth by the flood, He also destroyed a whole nation by fire and brimstone. Whether God uses another sinner to do that which would be reprehensible to us or some other disaster is no different. The Assyrian king was an ax in the hand of the Lord against his people. God in the Scripture commands his people to destroy whole nations; in other words, genocide (1 Samuel 15:3, Numbers 31). They were to destroy the nations in order to blot out the remembrance of them (Deut. 25:19). Jesus says that likewise you will also perish if you do not repent either.
