God does not play dice with the universe; He plays an ineffable game of his own devising, which might be compared, from the perspective of any of the other players, to being involved in an obscure and complex version of poker in a pitch dark room, with blank cards, for infinite stakes, with a dealer who won't tell you the rules, and who smiles all the time.

The gods of the Disc have never bothered much about judging the souls of the dead, and so people only go to hell if that's where they believe, in their deepest heart, that they deserve to go. Which they won't do if they don't know about it. This explains why it is so important to shoot missionaries on sight.
