Protestantism
The varying Protestant views of "hell", both in relation to Hades (i.e., the abode of the dead) and Gehenna (i.e., the destination of the wicked), are largely a function of the varying Protestant views on the intermediate state between death and resurrection; and different views on the immortality of the soul or the alternative, the mortality of the soul. For example John Calvin, who believed in conscious existence after death, had a very different concept of hell (Hades and Gehenna) to Martin Luther who held that death was sleep.
In most Protestant traditions, Hell is the place created by God for the punishment of the devil and fallen angels (cf. Matthew 25:41), and those whose names are not written in the book of life (cf. Revelation 20:15). It is the final destiny of every person who does not receive salvation, where they will be punished for their sins. People will be consigned to Hell after the last judgment.
