Whereas Judaism, for all the smiting G-d does, doesn't have a hell. Though to be fair to the NT, forgiveness is Jesus's whole schtick, but the penal system hardly seems forgiving. Maybe because of the deleterious legacy of Puritanism, and Calvanist predestination, with the idea that some people are born saved and others deserve their scarlet letters.
I concede, though I think this is a later innovation of the Rabbinate; Gehenna is an actual place, an ancient garbage dump, on the outskirts of Jerusalem. It is not referenced as a spiritual plane in the Torah like the Lake of Fire (Hell) in Christianity or Islam. It likely gained that interpretation under the influence of Platonism. I am not (yet) a Jew so I can't speak authoritatively to Jewish eschatology, but I think there's more room for give and take in the Talmud and Zohar (where Gehinnom is referenced) as it's the recorded wisdom of rabbis rather than Law itself. This is just my understanding based on my studies thus far.
That Jesus story comes from Rabbi Onkelos, a Roman convert who performed necromancy (!) to summon Jesus and ask questions about the afterlife. Apparently Gehinnom as described by the conjured spirit was indeed reserved for Jews who sinned; I think the unrighteous gentiles (not the Noahide) simply stop existing. They also got Shabbat and Yom Kippur off (I wonder if the summoning ate into Yeshua's break time.)
