First of all, Jews don't believe in the devil. Or in hell.
Second of all, Pharisees were the earliest Rabbis, not some cabal of conspiracists. They were scholars, jurists, and teachers. They plotted against no one, not even a heretic false messiah like Jesus. And when you denigrate them as evil, murderous plotters, you denigrate all Judaism by association, and you echo classic anti-Semitic canards used to oppress us for centuries.
Third of all, Jesus was killed by the Romans. Pharisees had nothing to do with it, because at that time the true Sanhedrin was not executing people. Which is why Romans had to organize false sanhedrins, made up of corrupted Sadducees and Herodian puppets, in order to pass of any executions as something other than Roman oppression.
How do I know? Because I have multiple degrees in Jewish Studies and Rabbinic Literature, and have studied both Jewish History and the development of Western religions, and I don't get my information from conspiracy theories and antiquated theological polemics.
