Do people come back from Hell?

If you were in Hell and the Pope decided that the particular offence you had been damned for was no longer that bad in your particular case, would that mean you had to be released and allowed into Heaven? And would you be entitled to some compensation? Perhaps even therapy for the probable post-traumatic stress? I mean who goes through x years of unbearable torture without some psychological fallout? If you weren't rehabilitated in some way you could be a liability always starting fights with the cool floaty people in Heaven,, which they might not find very heavenly, and which could lead to complaints and 'problems' in the place without problems.

But maybe if your sins are still pending a final decision as to their scale of mortality etc, you don't go to Hell but rather to some sort of holding complex until the decision is made. This might be 100 or 1000 years in the future, but of course God will know that it's going to happen and won't let you be subjected to any torture for something which He will eventually turn out to have approved of when his various popes realise it. This holding complex will therefore necessarily be a nice place that isn't too different from Heaven.

While we're at it there's something else I'd like to know. If the crucifixion of Christ brought about a new covenant between humanity and God, whereby humans could now be redeemed of their sins and granted safe passage to Heaven upon repentance and acceptance of Christ, then wasn't it sort of the responsibility of God to advertise this to all humans at the point when it became available? I mean why did he only let a few people know about it? I know they told other people and gradually over 2000 years a lot of people found out, but a lot of people died in that time without knowing and must have gone to Hell. Actually, some people still don't know up in the highlands of Papua New Guinea or deep in the rainforest in South America. So are some people still going to Hell every day because they haven't been told they don't need to any more?

I don't mean to be awkward or anything, but this doesn't seem quite fair to me. Are there any theologians out there who can explain these things to me?

And, if God is omnipotent, can He prove He doesn't exist?
