How does gospel of peter incriminate jews?

Jesus was an orthodox Jew. He didn't know any other religion. In his lifetime he probably didn't know any non-Jews. All his followers were Jews. He had no intentions of undoing his own religion or leaving it.. There have been quite a number of Jewish Messiahs in the history of the Jews, I would estimate 8 or 9. One of these Jewish messiahs was forcibly converted, under threat of death, to became a Muslim. As a Muslim leader he was very cruel to his former Jewish co-religionists.
