Gibson showed Pontius Pilate - who was eventually removed as Governor because of his cruelty - as being "conflicted". this goes against what we know about the historical Pilate. He contrasts this with the "Jooooos" who want to crucify Jesus. The majority of Jews were not involved in the Crucifixion. Also, the High Priest et al. were appointed by the Romans. They did not take one step without Roman approval. The Romans won the war, they got to write the history.
Although he was showing more concern for himself than compassion for Jesus, Pilate does show some conflicted feelings here.
Meanwhile Jesus stood before the governor, and the governor asked him, "Are you the king of the Jews?" "Yes, it is as you say," Jesus replied. When he was accused by the chief priests and the elders, he gave no answer. Then Pilate asked him, "Don't you hear the testimony they are bringing against you?" But Jesus made no reply, not even to a single charge—to the great amazement of the governor.
Now it was the governor's custom at the Feast to release a prisoner chosen by the crowd. At that time they had a notorious prisoner, called Barabbas. So when the crowd had gathered, Pilate asked them, "Which one do you want me to release to you: Barabbas, or Jesus who is called Christ?" For he knew it was out of envy that they had handed Jesus over to him.
While Pilate was sitting on the judge's seat, his wife sent him this message: "Don't have anything to do with that innocent man, for I have suffered a great deal today in a dream because of him."
But the chief priests and the elders persuaded the crowd to ask for Barabbas and to have Jesus executed.
"Which of the two do you want me to release to you?" asked the governor. "Barabbas," they answered.
"What shall I do, then, with Jesus who is called Christ?" Pilate asked. They all answered, "Crucify him!"
"Why? What crime has he committed?" asked Pilate. But they shouted all the louder, "Crucify him!"
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!"
Then he released Barabbas to them. But he had Jesus flogged, and handed him over to be crucified. Matthew 27:11-26
