I would suggest you gain a better understanding of what is "evil".
All things were made through him, and without him was not any thing made that was made. (John 1:3)
That is so inclusive that John states it both ways, in the positive and negative. All things were made through Him. There is nothing that was made without Him. It's very clear that everything is made by God for His divine purpose and plan.
Before we get into one of these fanatical, hand-wringing "God is not the author of evil" debate for which we both would agree, I would suggest reading this short article about Augustine on Evil . The writer is a very competent pastor.
Not interested. Thanks.
