@ Killman, I agree with Fr0d0 you are reinventing the story, you should read it and know the facts of the story. First the serpent was not a snake, where did you get that idea, second like Fr0d0 said they did have knowledge and they even knew right from wrong. God showed them the tree and asked them not to eat of it or they would surely die, Eve told the serpent that they would surely die if they ate the fruit from the tree, to do this Eve had to know right from wrong and the same goes for Adam. How is it you see that God is not being fair to them, He gave them freewill to choose how to go about their lives, sure He could have keep the tree out of the garden and allowed them to be zombie slaves or robot like, He did not do that though because He loved them and He wanted them to love Him through the freedom of choice that He gifted them with. The only way they had freedom of choice is if they were given a rule to choose to break. There is so much more to the story of Adam and Eve, I believe it's one of the really beautiful storys of God's love.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
