A problem exists when attempting to place Eden and the experience, thought life, and spirituality in line with what human kind display following the fall.
One must understand that the first Adam was in total fellowship with God and could, as no one has since, face God and visit as good friends. What has terrified humankind since the fall, as experienced by the Israeli at the mountain (beginning with Ex. 19), Mosses at the bush (Ex. 3), Isaiah's commission (Isaiah 6), and even Mary's admission ("who am I...") Adam did not experience prior to the fall. One might make a substantial argument that Cain and Abel were like Adam in regard to being able to interact with God, but the account isn't quite as clear as to the level of fellowship rather that God's interaction was over worship experience.
Therefore, the question of God creating "evil" cannot be resolved by looking at Eden.
Rather, one must ask was "evil" a creation or a manifestation?
The Scriptures clearly teach that God created all things (John 1:3, Colossians 1:16). That includes that enemy of believers.
However, one must not confuse creation and eternal perfection. When God created, He also organized, and established authorities. For example: In the animal kingdom, the authority of the "pack" is the alpha, the authority of the herd is the leader... Each authority gains that authority and demonstrates that authority by expressing skill and strength.
Evil was not created but was manifested when excess of dominance was desired. The alpha male in the animal kingdom may murder because of excess of dominance.
The same when that enemy of believers was disclosed with evil. Had evil not come to the garden, there would have been no fall.
Did God ordain, decree, will... for the fall to occur?
He didn't have too. He knew what would occur. He knew and therefore before the creation of this earth, Christ died. He provided redemption before the fall, just as He provided love before we knew how to respond in love.
God does not react to events. Example: Pharaoh was already hard heart, God just confirmed the hard heart into obstinacy.
Ok, just some random thoughts about some of the responses I recall on this thread.
