Please lay off the sarcasm. It is not what I said. God created, but many —most, I think— things are from secondary causes; God uses means to accomplish what he decreed.
I say that God caused that there be sin. I don't say that God created sin. Sin is a result of each person's uncontrolled lusts, "each person is tempted when they are dragged away by their own evil desire and enticed. Then, after desire has conceived, it gives birth to sin". If you can show that that scenario would have happened, had God not created the universe, be my guest. All things, to every detail, descend causally from First Cause. If there is such a thing as sin, God caused that there be sin.
Just as James said, God does not tempt anyone.
