The New Testament is clear that the execution of Jesus was a Roman decision, prompted by a collaborationist faction of the priesthood. What anti-Semites never consider in their ravings regarding the execution of Jesus is that question was settled most brutally by the Romans themselves by the destruction of the priesthood after the Revolt. "The Jews" did not kill Jesus, a couple of corrupted toadies backing the Roman government at best "advised" Pilate. They put him on trial, then handed him over to the Romans. Pilate based his decision on his own questioning of Jesus. The execution was for treason, not because Jesus ticked off the Jewish priesthood.
Your are contradicted by scripture:
Luke 23:
20 Pilate therefore, willing to release Jesus, spake again to them.
21 But they cried, saying, Crucify him, crucify him.
22 And he said unto them the third time, Why, what evil hath he done? I have found no cause of death in him: I will therefore chastise him, and let him go.
23 And they were instant with loud voices, requiring that he might be crucified: and the voices of them and of the chief priests prevailed.
24 And Pilate gave sentence that it should be as they required.
Nothing stands to contridict me. Those in the Praetorium were probably Herodian collaborators--the chief enemies of any Jewish nationalist movement.
The New Testament only tells one part of the story, namely the perspective of a then-minor Jewish cult.
It was Pilate's decision, alone. Secular, brutal and totally Roman.
