Well, that is an interesting, thought-provoking scenario, and I can understand where you’re coming from on it. But I think, as you mention, that it’s a matter of the scenario being “the world’s perspective,” and that what’s being looked at about them is, from maybe quite a distance, their most visible good and bad works. But perhaps the person who seems to publicly rate a 9 would be rated much lower by at least some of the people closest to him, a very likely scenario if, despite all that he’s apparently been blessed with, he has out of the evil of his heart (as the Bible says the human heart is naturally deceitful above all things) time and again rejected the truth presented to him that he’s a sinner who is natural evil and separated from God unless he accepts Jesus as his savior, and maybe the person who only seems to rate a 6 (and correct me if I’m wrong, that would probably be to the average middle or upper middle class white person) would, after his conversion to Christ, be known among those around him as a humble, good-hearted servant to everyone around him, one who studied God’s Word to show himself approved by him, and a very different person than the one who had once been a violent criminal.

Regarding the second, I believe the lost suffer the second death. As described here:
