Is not all that irrelevant?Are we judged for Adam's sin or for our own sins? Are the unredeemed paying for Adam's sin or their own? The imputed sin of Adam to us is an external quality, the ruin of our standing before God. An objective reckoning. Original sin is the ruin of our character--internal.
All that matters is whether one is guilty or not, whether Christ has paid one's sin debt or not.
Christ paid for all our sin and guilt, and judgment is separation from God for eternity, regardless.
