Even of the rich man in Hades (Lk.16:19-31) it is not stated how long his torments would last while there. Or denied that they could end while still there. Nor is it denied he could be saved while still in Hades. The rich man's Saviour is in Hades:
"If I ascend up into heaven, Thou art there; If I make my bed in the nether-world (Sheol = Hades), behold, Thou art there." (Psalm 139:8)
The rich man is called "son" (literally, "child") :
Lk.16:25 “But Abraham replied, ‘Son, remember that in your lifetime you received your good things
"Here, too, was one who, even in Hades, was recognised as being, now more truly than he had been in his life, a “child” or “son of Abraham.” (Comp. Luke 19:9.) The word used is the same, in its tone of pity and tenderness, as that which the father used to the elder son in the parable of the Prodigal Son (Luke 15:31), which our Lord addressed to the man sick of the palsy (Matthew 9:2), or to His own disciples (John 13:33)." Ellicott's Commentary for English Readers
The rich man in Hades is receiving the Word of Truth from Abraham. If not to lead those there to repentance & salvation, why would anyone in Hades be receiving such truths.
When it is implied that the rich man is where he is due to his lack of compassion for his fellow man, in particular Lazarus, he responds positively by turning his attention from himself to his brethren still alive & requests that they be warned about Hades. Is the rich man turning from his selfishness & showing concern for others?
The story speaks of a great gulf fixed stopping the transfer of persons from one place to the other place. It does not say this gulf will remain in place forever. Only that at that moment in time it was so. Possibly the chasm barrier refers to the unrepentant state of those in Hades, & that once they repent the barrier stopping any individual from leaving is removed. Nor does the passage deny the possibility of salvation to the rich man in Hades while he remains there.
" “And besides all this, between us and you a great chasm has been fixed, so that those who want to go from here to you cannot, nor can anyone cross over from there to us.” "
" "So even if we made the mistake of trying to extract from the details of this parable a position on the issue of whether there will be further chances, there still wouldn’t be much cause for taking this passage as supporting the doctrine of no further chances with any force at all. For as long as the [one] who believes in further chances sensibly allows for the possibility that, while punishment is occurring, those suffering from it can’t just end it any time they want, she can make perfectly good sense of the words this parable puts into the mouth of Father Abraham. After all, if a road has been covered with deep enough snow drifts, we’ll tell someone who must drive on that stretch of road to get to where we are, “You cannot cross over from there to us.” We’ll say this quite properly and truthfully, even if we know full well that the road will be cleared in a few days, or that, in a great enough emergency, a helicopter could be used to get across to us even today, if, say, we’re at a hospital. [But doesn’t that show that there is a sense, then, in which they can cross over to us? Yes, there’s a perfectly good sense in which they can, and a perfectly good sense in which they cannot. For enlightening and accessible explanations of the meaning of “can” and related words, I recommend Angelica Kratzer’s “What ‘Must’ and ‘Can’ Must and Can Mean” (Linguistics and Philosophy 1 (1977): pp. 337-355) and example 6 (“Relative Modality”) of David Lewis’s “Scorekeeping in a Language Game” (Journal of Philosophical Logic 8 (1979): pp. 339-359.]"
The duration, nature, intensity & purpose of the torments the rich man was suffering are not revealed in this story. His torments there could have lasted less than 5 minutes.
We might also want to consider these passages in the same book of Luke's gospel:
Fear not, said the angel who announced it, for, behold, I bring you good tidings of great joy, which shall be to all people. Luke 2:10.
Glory to God in the highest, and on earth peace, good will toward men. Luke 2:14.
Luke 3:5 Every valley shall be filled,
and every mountain and hill shall be made low,
and the crooked shall be made straight,
and the rough ways made smooth;
Luke 3:6 and all flesh shall see the salvation of God.’”
Luke 4:18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,
But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be sons of the Most High, because he is kind to the ungrateful and wicked. Luke 6:35
Luke 15:3 And he spake this parable unto them, saying, 4What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it?
Luke 15:8 Either what woman having ten pieces of silver, if she lose one piece, doth not light a candle, and sweep the house, and seek diligently till she find it?
Lk17:4 Even if he sins against you seven times in a day, and seven times returns to say, ‘I repent,’ you must forgive him.”
Luke 16:19-31 rich man in "hell"
