SH: “In fact, we often “laugh” at those who we percieve to be doing Mitzvos in order to get Schar”
I once heard a lubavicher denigrating those who don’t do aveiros because of the fear of punishement, and saying that in lubavich that is not why we don’t do aveiros. (I have actually heard it far more than once, but in this case there was a good rejoinder, as I am about to write). A serious lubavicher talmid chochom whom I respect (yes, there are a few!) was present, and he commented, “That’s because in lubavich we don’t believe in Gan Eden or Gehennom.”
Think about it. So often people claim that it is wrong to consider schar ve’onesh, but that is not because we are on a higher madreiga. It’s because we are on a much lower madreiga and don’t have much yiras Shomayim of even the lowest type.
