CS, does the Lubavitcher rebbe bring anyone else who says that yeridah letzorech Aliyah applies to how horrible geninnom is vs. how big their olam haba will be? I’m sorry, but that sounds completely untenable. If someone is in a worse part of gehinnom, it is to cleanse him of worse and deeper sins than others. Like a stain on the majority of a shirt vs a tiny blemish. After he’s done getting his sins burned off, he’s at the most, the same level as the one with the small sin.
but besides the lichluch hachait, there’s another factor. The time a tzadik spends doing mitzvos vs the time the rasha spends sinning. In this world, we grow; we cannot grow in olam haba. The more we accomplish here, the more we get there. The time and energy spent sinning could have been used for avodas Hashem; that, the rasha is missing out on and will be missing it forever. It is lost potential. Of course, teshuva makes him better than the tzadik gamur in some ways, but that’s an avodah that is done here, not there.
You’re convincing me more and more of the diversions of the Lubavitcher rebbe from basic jewish hashkofa.
