Here is where you just don't get it, one could contend that creating good is doing good very easily, but trade the word evil for good and you reject the idea.
Why would I reject that? God is Good, Everything He does is Good, even when He says He creates evil and darkness, it's still All Good because God IS Good, Just Like God is Love, it's Who He is by nature. All things that He does Has purpose, unlike man when he does evil it has no purpose but to inflict pain, or grief etc...
Again I say as Paul said, when he/He chose to do good, evil was present with him/Him, so it was with God, that's how God can say He creates evil. Since He is by nature Good and when He does something it is Good, then Evil is/was a presence with Him....Just like us, when we are being led by The Spirit of God there is a good possibility that evil will be a present factor to try and distort, deceive, twist, and even kill what is Truth.
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that it is good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21
I find then a law, that, when I would do good, evil is present with me.
