Todays Daf (Bava Basra 116) says that someone who has no sons to inherit him is a Rasha. The Gemara tries to figure out who said this, the Gemara suggests that it was R' Yochanan but rejects that possibility because R' Yochanan's ten sons all died in his lifetime and R' Yochanan would not have considered himself a Rasha. It is fasciniating to see how literally the Gemara takes this idea, it coul have said that R' Yochanan was an exception etc. but no the Gemara takes teh statement literally.
This is astounding. According to this opinion in Chazal, R' Yochanan was a Rasha, Rashi was a Rasha, the Chazon Ish was a Rasha, the Lubavitcher Rebbe was a Rasha, etc. because none of them had sons who inhereited them. How ca anyone make such a silly statement?
