Torment in hell is identified as everlasting punishment in Matthew 25:46.
Eternal Punishment does not mean eternal torment. Its the "second death" from which there is no resurrection ---for all eternity their way back no longer exists. They died "the second death". Their place before the face of God has been eternally destroyed (2 Thess. 1:9).
It does not logically follow all eternally punished with banishment must continue to exist.
The goats are cast into the Lake of Fire, which was created for Satan and his angels, and it is eternal. It does not follow every goat will be eternally tormented. Each cast there in were judged, and according to their deeds are punished.
There is no reason to suppose God changes His standards during different judgments of the lost. Punishment is according to deeds:
12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. (Rev. 20:12-13 KJV)
The wicked "shall have their part in the lake", how big a part is according to deeds. One size does not fit all:
"But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part (3313 μέρος meros ) in the lake which burns with fire and brimstone, which is the second death."
(Rev. 21:8 NKJ)
3313 μέρος meros
Meaning: 1) a part 1a) a part due or assigned to one 1b) lot, destiny.
