Hell

Hell was believed by some cultures to be the afterlife in which sinners were punished.

Concept
Hell was embedded in the minds of species like humans through religions like Christianity, the opposite afterlife being Heaven. The Seventh Doctor claimed there was no such place as Hell.

(AUDIO: Absolution) The Twelfth Doctor claimed not to be scared of Hell as he believed it was "just Heaven for bad people". (TV: Heaven Sent)
