“It may also mean that Eve sinned before the Fall by choosing to act outside of her ‘gender role’ and out from under her ’spiritual leader.’”

Eve was not instructed to follow a leader. Adam was not instructed to be a leader. Adam was instructed to tend the garden – protect it. In that he failed but it was not a matter of sin. He just allowed danger in. Their only sin was in disobeying God’s direct instructions.
