According to the Gospel accounts, Jesus was condemned to death by Pontius Pilate, a Roman official, but the Jewish high priest and other high officials pressured him into doing so. The Pharisees were not involved. Elsewhere in the Gospels they are portrayed as antagonistic to Jesus but they were not part of the power structure.
The link I posted says all 4 gospels either explicitly or implicicity say Jews killed Jesus but because they weren’t allowed to do it themselves they enlisted Romans to do the deed
So you either have to say the gospels are liars or you have to accept that is what happened
And it is not a stretch for scholars to believe in retribution for these claims from the Christians that the Talmud said Christian Jesus is boiling in excrement
The fact that Hitler tried to kill all the Jews doesn’t rewrite the Gospels
You are right, it was the Sadducees.
