The problem of Hell is an ethical problem in religion in which the existence of Hell for the punishment of souls is regarded as inconsistent with the notion of a just, moral, and omnibenevolent God. It derives from four key propositions: Hell exists; it is for the punishment of people whose lives on Earth are judged to have sinned against God; some people go there; and there is no escape.
There are several major issues to the problem of Hell. The first is whether the existence of Hell is compatible with justice. The second is whether it is compatible with God's mercy, especially as articulated in Christianity. A third issue, particular to Christianity, is whether Hell is actually populated, or if God will ultimately restore all immortal souls (universal reconciliation) in the World to Come. Lastly, if Hell ceases once the wicked are destroyed or consumed. Criticisms of the doctrines of Hell can focus on the intensity or eternity of its torments, and arguments surrounding all these issues can invoke appeals to the omnipotence, omniscience, and omnibenevolence of God. In some aspects, the problem of Hell is similar to the problem of evil, assuming the suffering of Hell is something God could have prevented. The discussion regarding the problem of evil may thus also be of interest for the problem of Hell. The problem of Hell can be viewed as the worst and most intractable instance of the problem of evil.
Almost no forms of Judaism share the traditional majority Christian belief in the immortality of the soul, therefore Sheol (Hades in the Septuagint, "the grave" in many instances in the King James Bible) is simply the destination for all the dead, and no "problem of Sheol" exists. Gehenna, found in the Mishnah, is the destination of the living and raised wicked at judgement day, and the place of either of destruction, in the Mishnah, or in some rabbinical texts eternal torment, which would potentially create a "problem of Gehenna."
