I seem to have picked up this idea through “cultural osmosis”, but can’t think of an official source on it. Then some questions came up in a debate that seemed worth considering. The idea is that at their judgement, when God lists to them their offenses, people feel compelled to acknowledge each one with a “yes”. They know each one wrong and deserving of hell. This in spite of all the excuses and defenses one comes with in life for their sins.
Also people are acutely aware that their purpose in happiness was to be found in God. This is what makes separation from God the primary torture of hell. So now someone who has always hated God suddenly longs for Him. If so, wouldn’t the possibility of such a radical change make repentance possible too? If not, couldn’t they find hell somehow “satisfactory” with a misotheistic “good riddance”?
