Good theology would tell us that God set the scene so they would fall to fulfill his eternal purposes. Their dying brought the miracle of the resurrection. The world exists as it does because God wanted it to, not because Adam and Eve wanted it to. He is the one with all knowledge and designs the purpose for which things exist and the condition in which they exist as they pertain to truths about salvation.
The traditions of orthodox sectarian creeds teach of a self-existing God that acts in a random non-purposeful way. Their stated reason for the creation was so God could have someone to glorify him and this was for his own will and pleasure. Was he not already glorified enough and pleased with his existence?
Without the fall and therefore death and sin, there would be no Christ, no atonement, and no resurrection? My Christian faith does not concur with those scholars. The Bible teaches that Jesus was foreordained from before the foundation of the world to be our Savior. Even though Adam and Eve introduced death and sin, the consequences of those events were already dealt with.
Traditional theology doesn't recognize that death was the consequence of partaking because God wanted us to have eternal life through his Son. Without birth into mortality, there could be no agency or exaltation. He ordained family life for the fulfilling of his plan.
With the fall they were now capable of exercising faith in their Redeemer and the glorious eternal life he would deliver to them and their posterity. It would appear that Adam had pretty much decided not to eat the fruit on his own. God allowed Satan to hasten the process needed in order to begin the real salvation of Adam's and Eve's souls. Their bodies wouldn't be perfected until they were resurrected. Their character would also be perfected through knowledge, choice, repentance, mercy, and grace.
Our purpose here on earth is to gain a physical body and see if we will overcome evil by our own choice and choose to follow Jesus. The war in heaven continues here and now over freedom and choice.
We are given power over Satan and his hosts through faith in Christ. He will be overcome and cast to his final prison in the end. It will be done in the same manner as the pre-earth war. "And they overcame him by the blood of the Lamb, and by the word of their testimony". Revelation 12:11
