Throughout Meseches Avodah Zarah, we are told of three times when Rebbe Yehudah Hanasi (or simply, “Rebbe”) cried. Each story has a similar outcome that caused Rebbe to come to tears. The first appears on daf 10b, where the gemara recounts the story of Ketia bar Shalom, a Roman advisor to an unnamed Caesar. The Caesar explained his intentions to kill all of the Jews. Ketia explained exactly why the Caesar should not go through with his plan. While the Caesar agreed with him, he had Ketia killed. On the way to his execution, Ketia circumcised himself and repented for his sins.
