Damnation

Damnation is a common concept in religion where a certain evil deity will torment an individual for eternity.

Christianity
In conservative Christianity, damnation is generally seen as one who does not accept Jesus Christ as their Lord and Savior will go when they die, especially grown-ups who know about the bible. In mainline Christianity; it is generally seen as a place where spirits manifesting much evil go when they die. In Liberal christianity and Universalism; on the other hand; they generally reject the existance of Hell or damnation period.

Islam
In Islam; damnation follows a similar suit to Christianity. In conservative Islam; generally only a select few will not be damned or only those who accept Islam. Others reject damnation period.
