Whether or not Jesus existed
Jesus pointed out bad things that Rabbis did
Then he was crucified
You can take that as a symbolic story about Rabbis ordering the government to execute people who point out their bad behavior or a literal historical event involving Rabbis who ordered the government to execute people who pointed out their bad behavior
Whether or not Jesus was crazy for letting people worship him as God or really was the incarnation of God
I respect him for pointing out Jews
