As for the Jesus quotes, I dont think its news that we Jews dont think highly of Jesus, while the Gemara may not be refering to your Jesus, it was a very common name at the time, if it is it shouldnt really come as a great surprise. Chaim follows a lenient opinion in regards to Christianity, the opinion of the Meiri, but other Jews like Lubavitch follow the opinion of the Rambam, that non-Jews should follow the Sheva Mitzvot Benai Noach, and through that serve Hashem, and it is our duty to bring the Goyim to the Sheva Mitzvot Benai Noach.
Here is what I think of the situation with Jesus.
Jesus, or to be more precise, Yeshua ben Yosef, was:
1) a Jew, first and foremost
2) a patriot
3) someone, who saw the suffering of the Jews under Roman occupation and witnessed the hopelessness of the struggle of Jewish people against the occupants
4) someone, who witnessed, along with other Jews, that Messiah was not coming despite the tragic condition of his people
5) someone, who understood that you could not defeat the strongest army of Romans with violence
6) someone, who witnessed how Jews were losing hope and faith because Messiah’s “delay”
7) someone, who took a risky path of claiming divine nature to save his people
8} someone, who could not save Jews, but refused to give up his claim
For me, Jesus is not a Messiah, but definitely a son of my people, who wanted to free Israel.
He is a lesson for me that Jews should not rely on G-d’s messengers when they can do the job on their own. They should not wait for the Messiah, in order to become righteous. But become righteous now, and that total holiness of the people will be equivalent to the coming of the Messiah.
