I believe there is evil in the world, but God is not the evil one. The evil one is Satan, Jesus said so.
Is God capable of eliminating Satan if He choose? It seems to me if you allow evil to continue you are culpable.
Satan has been defeated. Haven't you read the book? Man disobeyed God and gave up his authority on the earth. God redeemed man. God has done it all. We're the guilty ones, not God. Do you believe in sin and understand what it is? Do you understand God is holy, sinless?
If Satan has been defeated why is there still evil in the world? The obvious answer is that God chose to create a world knowing it would be filled with incredible pain and suffering. That sounds like evil to me.
We are never to think of God's power in terms of what he could conceivably do by the exercise of what we may call sheer omnipotence which crushes all obstacles in its path. We are always to think of God's power in terms of his purpose. If what he did by sheer omnipotence defeated his purpose, then, however startling and impressive, it would be an expression of weakness, not of power. Indeed, a good definition of power is "ability to achieve purpose. Does it fulfill its purpose?
God's purpose isn't to achieve a certain outcome. God's purpose is to achieve a certain outcome under certain conditions.
“Religion’s Answer to the Problem of Evil”
The Bible has several literary types; allegorical, historical, law, poetic, prophetic, epistle and proverbial. I'm sure others may add or subtract to this list, but this is a pretty good start. When trying to understand the meaning of passages it is helpful to understand which literary type one is reading and also to place or read the passage in the proper historical light.
Let's start with the tree of knowledge of good and evil and the fall from grace. Genesis is allegorical. It starts with the allegorical account of Creation. After every step God would say "and it was good." So basically everything God created was good. Which makes sense because things like evil, darkness and cold or not extant. They don't exist on their own. They exist as the absence of something else. Cold is the absence of heat. Darkness is the absence of light. And evil is the absence of good.
Man knows right from wrong, but when he violates it, rather than abandoning the concept of right and wrong, he rationalizes that he didn't violate it. After Adam and Eve had sinned and realized they were naked, they hid when they heard God coming. They hid because they knew that they had done wrong. Then when God asked point blank if they had done it, they rationalized that it wasn't their fault. Adam, did you eat the apple? The woman you made gave it to me. Eve did you eat the apple? The serpent deceived me.
Man is the only animal capable of knowledge of good and evil. No other creature has this concept. Sure animals can have empathy, but not like man. Animals function on impulse and instinct. Man functions on these too, but in man's case he has the unique ability to override his impulses and instinct for the sake of good. That is free will. It's a choice. Everything is choice.
I don't believe that Genesis is implying that had Adam and Eve never committed the original sin, we would live in paradise forever. I believe Genesis is saying that man has the capacity to do good and evil. So then the question begs why did God create such a world. I believe that that is an artifact of life. In other words, I don't believe God had a choice. It is part and parcel of the extant nature of good. I know people will howl that I said God had no choice but the reality is there are things God can't do. For instance, God can't oppose Himself; He can't go against His own nature. He can't go against his purpose.
So there are two very interesting things which come out of free will. One is that evil has the effect of making good better. It's like salt and sugar. Salt makes sugar taste sweeter. We are told elsewhere that He uses all things for the good of those who love Him. Among other things the Jews discovered is that there is meaning in suffering.

The other interesting thing is that good has no meaning unless there is evil. In other words, it is not virtuous if you are forced to be virtuous.
In closing, man prefers good over evil. We don't do evil for evil's sake. We do evil for the sake of our own good and when we do, we rationalize that we didn't do evil. But from these acts, goodness will arise and we will be stronger for it. It is a self compensating feature whose sole purpose is to propel consciousness to the next rung in the anthropological ladder.
