Didnt Spectre refrain from casting judgement on him specifically because Joker couldn't understand morals/ethics?I forget the particulars. I thought it was basically: Joker understood what actions were acceptable and completely unacceptable, and was smart enough to know how to use those actions to manipulate people, cause fear, etc, but couldn't place them in 'right'/'wrong' contexts.
This was volume 3 issue 51, Corrigan was going to judge him, but later decided not to, because the Joker is a sociopath and "He does as he pleases without any concept of right or wrong." But made him feel the pain of all the souls he's destroyed, and though that Joker will bury the memory deep in his erratic mind, it might one day give him a sense of the lives he destroys.
Later there was another encounter in JLA DOJ follow-up, when Martian Manhunter took them all there mentally, it was merely to show Hal Jordan that there was good even deep inside of someone like the Joker. It was an issue where Hal was struggling with the idea of being the Wrath and who to judge and not to judge. It showed that everyone has sins and goodness in them.
Later on, during another encounter in volume 4, Hal was no longer The Wrath, he was The Redemption. So he wasn't there to cast judgement. But when he tapped into Joker's mind, it brought out the madness in his own mind/Parallax. Was one of the early moments of him beginning to forgive himself.
