Adam was a unique man, in that he was the only one created sinless. Eve was in the same state, but she was formed from the man. You can not posit pre-fall Adam into our status.
Adam was born posse peccare posse non peccare. We weren't born in that status.
Look at what transpired in the Garden. God gave Adam one simple command, don't eat of the ToK. That's it. There were no hoops to jump through, no alternative things he needed to do, &c. All he was commanded to do was not eat of that tree.
In comes the serpent and tricks Eve. She knew what would happen to her and Adam if they ate of that tree, so Adam must have told her what God told him. She was not yet taken from Adam when God gave him that command. Yet, when the serpent said she could become like God, this happened...When the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was desirable to make one wise, she took from its fruit and ate; and she gave also to her husband with her, and he ate.[Genesis 3:6] She saw that it could make her wise, and she believed that serpent hook, line, sinker, rod and reel and boat. Adam was right there with her and he did not stop her. Adam chose his wife over his God, and that shows his heart was not right before God when he took the fruit and ate it.
Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death.[James 1:15]
