If Adam and Eve knew exactly of the harsh consequences of eternal banishment unto a land of misery for them and their offspring as a result of falling from grace with the Creator, would they have sinned? Looking at the choices that people make today, yes they would have, because the human mind is partly of a selfish and willfully ignorant nature. It's just my own personal belief, but I believe that giving humans free will was the result of the Creator's favor in us but was a choice that even He had not known of the consequences that would follow, in a world of otherwise fixed cause-and-effect. Our banishment is the eternal punishment for being a failed creation who betrayed His trust and caused Him irreparable suffering, and that God interferes at times in our banishment because of guilt for our creation and partly because of some remaining love for us. Otherwise we are left to do as we can with His guidance. So no, I do not believe in a Creator that is all-knowing, because He would not have gave us free will. I do, however, believe He is benevolent, but that his benevolence to us is limited because of our corrupted nature.
