Now i am firstly not arguing about Hell being unnecessary, there are i really believe some souls who are so wedded to sin that they will never repent even if they saw a vision of Heaven and it’s glories. What i am saying is does the idea of Hell motivate people to do good that they would otherwise not do? The Catholic Encyclopedia seems to think so " if all men were fully convinced that the sinner need fear no kind of punishment after death, moral and social order would be seriously menaced. This, however, Divine wisdom cannot permit." I mean is it not the grace of God that causes the person to be good in the first place, that a person could theoretically be good out of their own will without any expectation of reward or fear of punishment?
We see that in many parts of the world across history where there was little if any fear of Hell, at least an eternal Hell. We also can look at the past across many Christian countries and see many instances of immorality, clearly the fear of Hell was not keeping them from doing evil, could they have done more evil had they not believed? perhaps but the matter of the fact is that when someone does good they do it because God has given them the grace to do it, not because they have a fear or an expectation of a reward so is it time we saw the argument that the fear of Hell makes the world a better place as an outdated one?
