Is Hell the end?

No, all that are in Hell will be judged by God at the Great White Throne Judgment after Jesus Christ has come back to this earth to rule and reign for 1,000 years. They will be judged for their wickedness and then cast into a place called the Lake of Fire. We do know that it is an eternal judgment. We also know that it swallows up Hell. The Lake of Fire will be eternal suffering.

Rev 19:20 (KJV): And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.

Rev 20:10-15 (KJV): And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever. And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. 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. 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. And death and hell were cast into the lake of fire. This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire.
