Some of these are also equivalent of the underworld (land of the dead), the place where those who have died go instead of being the place where only the sinners go to be tormented for all eternity or whatever each particular one makes it to be.

Some belief systems say that hell itself is not eternal but rather a temporary, but very long, punishment that will eventually end. In these belief systems, the end of hell means either merciful and final absolute destruction for sinners or that their punishment is finally sufficient their souls are cleansed and worthy of heaven. Either way their is no escape for Satan and his demons who are cast into the "pit", and area that is eternal punishment.

Note: According to Judeo-christian traditions, Sheol is where all the dead went. The unrighteous experienced torment but the righteous were conformed in "the bosom of Abraham". An impassable gulf exists between the two in Sheol. Gehenna is quit a different concept and is the ultimate destination and punishment for the wicked. Among Christians, beliefs are split as to the exact nature of Gehenna and whether people still go to Sheol or if they go to Gehenna or Heaven instead. But these details are not a primary concern amongst most groups.

Another view is that there is no hell proper, but after the destruction of the corporeal universe, simply Heaven and everything outside of it will be left. The wicked must dwell outside andl be tormented with the sight of Heaven.
