Here is an analogy even a Jehovah's Witness can understand.
SOJ, consider this.
As a parent, if you had a child (of young age) who was with you in the kitchen while you were preparing a meal, and the stove was hot, and they went to reach for the stove and were about to burn their hand. You sternly warn them not to touch the stove because they will burn their hand... yet they do so anyway and burn themselves.
Do you punish your grandchildren or great-grandchildren because of what your child did?
Allegedly according to Christian Bible doctrine, Adam ate from the Tree of Life after being warned not to by God. Did God punish just he and his wife.. the perpetrators of the crime? No. He instead declares a death sentence to all humanity, and punishes BILLIONS of people, generation after generation, because of the actions of two.
According to all Christian doctrine, everyone alive after that period never had the choice. All suffer because of Adam's mistake? Yet as an excuse you say that this is temporary so as to garner a better reward later? Who are you kidding? Some loving God you got there. Jesus allegedly claim to atone Adam's sins. So thousands of years of suffering and death are so that an Almighty God can prove a point?
Wake up and stop following a fairy tale.
