God created Evil for our GOOD.
I think I follow what your trying to say in the thread, but God is adamant that he did not create evil or sin, and I think we should not word it like that just because context is difficult, I think what your meaning is He did allow sin and evil to be in the world? which I would agree with.
I think when you follow the logic through, God knew we were going to be sinners, He knew Adam was going to sin, He could have made things so that Adam was not going to sin, but did not, and then as soon as I point out God must have wanted sin in the world people go into conniptions, as if I have slandered God.
Witnessing to people a common theme I run into is they dont like the God of the bible, a God who allows so much pain and death to happen to people, a God who allows children to starve and die, and violence to overtake good people, especially when loved ones are taken from them, when hearing these sentiments I actually agree with them that God does indeed allow it to happen, and apparently it surprises them as others just argue the point, I point out I can understand their animosity towards me as Im a representative of God whom they are angry with, which alot of the time gets me a foot in the door to explain how I see things and how on the other side of the coin God does also hate death and sin, which then leads on to the sharing of the gospel sometimes.
All I wanted to point out is even non Christians see God as sovereign and in charge of everything including allowing sin and death in the world even if its subluminal, yet some Christians seem to me go into denial mode, as if their loving God would not allow such atrocities to happen and come up with lots of other reasons like it must be because Satan and his cohorts are causing it all etc etc Of course if they could get things to happen under Gods nose that He did not allow then they are elevating Satan and lessening God.
He is the Potter we are the clay we have to accept His ways as righteous for even if we dont comprehend why He does what He does we know they are.
Anyway I see the tree of knowledge as a real tree but figurative in the fact that it was the disobedience that opened Adams and Eves eyes, in other words it could have been a stone of knowledge and God could have commanded Adam not to pick the stone up! Adam who had no sin nature could not disobey Gods command unless there is a countermand from another source (which God allows planned to happen) and once Adam had a choice and disobeyed by picking up the stone, now the realisation of Doing what God says or not is now an innate choice, they now know they can do good or evil. Of course the tree and fruit have more figurative meaning throughout the bible so its the best representation and Im just using a stone trying to explain how I see it.
Anyway interesting topic, and interesting questions for I seem to enjoy hearing others thoughts about them
