I have some problems with this.
First, if there's unlimited time, then it doesn't matter how fast it goes.
Second, it's bad enough to torture people forever, but for them not even to remember why?
The reason you have problems with this is because a loving God does not torture people.
Hell is the grave and there is no consciousness in hell ... all are in a dormant state until Jesus returns and then the 1st resurrection (the saved) happens. The second resurrection (the unsaved) happens later and then all are destroyed for eternity (not tortured).
Ecclesiastes 9
5 For the living know that they will die,
but the dead know nothing. They have no further reward, because the memory of them is forgotten.
1st Thessalonians 4
The Return of the Lord
13Brothers, we do not want you to be uninformed about those who sleep in death, so that you will not grieve like the rest, who are without hope.
14For since we believe that Jesus died and rose again, we also believe that God will bring with Jesus those who have fallen asleep in Him.
15By the word of the Lord, we declare to you that we who are alive and remain until the coming of the Lord will by no means precede those who have fallen asleep.
16For the Lord Himself will descend from heaven with a loud command, with the voice of an archangel, and with the trumpet of God, and the dead in Christ will be the first to rise.
17After that, we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord.
18Therefore encourage one another with these words.
Those in the 2nd resurrection.
Malachi 4:1,3. "For behold the day is coming burning like and oven, and all the proud, yes allude wickedly shall be as stubble. And the day that is coming
shall burn them up, says the Lord of hosts,
that shall leave them neither root nor branch. . . You shall trample the wicked for
they shall be ashes under the soles of your feet."
