I agree, too, except I'd change one thing. To live a Christ rejector in the clear face of plain, accountable truth of who the Christ is is unpardonable.
The point being, whether dead or alive, there comes a point where you can't reject the testimony of the Holy Spirit about the Christ when God knows you are fully responsible for that knowledge. I submit to you that the irreversible death people die for rejecting the Christ happens while they are still very much alive. The only thing left for them is to await the Judgment.
