I fell a little behind in my reading and as I caught up, I kept noticing stories about hurt feelings and how the Sage whose feelings were hurt got even. Often, by excommunicating the offender. It is a clear pattern. Since most of the stories were after the destruction, I thought of the Bar Kamma story as the reason for the destruction of Jerusalem. Getting even for being embarrassed destroyed so much. But the stories we have don't seem to be critical of this attitude, even though being forgiving is shown as a virtue in some cases.
What is the purpose for telling all these stories?
