Peter's sermon to the Jews on Pentecost, "This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross." Acts 2:22
Mt 27:22-25 Pilate said to them, "What then shall I do with Jesus who is called Christ?" They all said to him, "Let Him be crucified!" Then the governor said, "Why, what evil has He done?" But they cried out all the more, saying, "Let Him be crucified!" When Pilate saw that he could not prevail at all, but rather that a tumult was rising, he took water and washed his hands before the multitude, saying, "I am innocent of the blood of this just Person. You see to it."When Pilate saw that he was getting nowhere, but that instead an uproar was starting, he took water and washed his hands in front of the crowd. "I am innocent of this man’s blood," he said. "It is your responsibility!" All the people answered, "Let his blood be on us and on our children!"
That should pretty much settle the issue.
