I think there is another way to interpret it... both Neo and Real.
Adam and Eve did not know if the things that they did were good or evil...
They were prehistoric.
They had neither knowledge of evil OR good. They were animals and naked. Kind of like Frank... hehe
Yet, God overlooked this because of grace and humans were in harmony with the earth. God did not want humans to feel evil and shame...
When their eyes were "open" they realized they had been rather uncivilized. Again like Frank...
Yet when they realized they suddenly had the capacity for evil... well they began at the simple evil stuff then they graduated to the more sophisticated evil of high treason against the only God at the time.
They gave dominion over the world (which God had given them) to the devil, why? Because they "knew" it was evil and they choose to partake.
This is why it is called "the fall" of Adam and Eve? Because they purposefully and consciously fell into evil. The only other fall in the Bible that is compared to the expanse of the fall of Adam and Eve is the fall of Lucifer.
They chose the greater of two evils and the lesser of two goods.
