It must be admitted that sin is a part of God's eternal plan, for He works all things according the counsel of his will (Eph. 1:11)… While God ordains the evil choices of free moral agents, He does not thereby incur blame or wickedness, because He does not directly or efficiently cause any evil. He brings about the evil actions of man through secondary causation according to their own wicked desires. God is absolutely sovereign, and man is entirely responsible for his actions.
John MacArthur
