Dear RBZS,
I apologize for not replying sooner. Your posts do not show right away. [I don’t know if it is the site. Or my use of it. Either way it is weird.] I say your last post before yom tov. But I only say the other two today.
The Chassam Sofer is taking about a tzaddik that the people rely on. It specifically refers to a known leader that people are welcomed to partake of the tzadik’s assistance. See there for a discussion about Nadav and Avihu’s lack of involvement with the common people. There is no mention of the term korbonos. And it has no bearing on the passing of young people who were anonymous to us.
Your newer source is interesting, thanks for sharing it. Note how it compares the passing of the tzadik to yom kippur, not korbonos. I would like to read the whole piece, as it leaves me very puzzled. What lis lifting the Jews up to that level?
