It is 33 AD in the Common Era, and the Romans have control over Israel and various other countries. Many of the citizens under their rule are little better than slaves and deserve the cruelest treatment then known to man. The Jews are barely unworthy of consideration by Caesar, and he carelessly murders them without end. God's people are underneath a yoke of hardship above any their people had experienced before, including the many chastisements placed upon the people of Israel during past captivity.
And then, here comes a man claiming to be the Christ—the Deliverer, Savior, Redeemer—the man who would free them. But He didn't free them from the Romans. Instead, He, who proclaimed to be their Messiah, let Himself be led like a lamb to slaughter. He, who was supposed to lead them out of captivity, stood meekly beside the Roman prefect, Pontius Pilate, without raising a fist. He, who was to free them from the whip allowed Himself to be beaten by a nine-tail whip.
It's because He who was the ultimate Messiah needed to deliver Himself into the hands of His enemies (the hypocritical Sanhedrin) and the Jews' enemies (the Romans) to rescue all—not from physical captivity at this time but from spiritual captivity and physical death.
What's interesting is that these cruel Romans, who had no problem sending a Jew to the cross to suffer the ultimate torture, experiencing agonizing pain in their hands and feet while suffocating slowly as everyone below mocked them, were hesitant to send Jesus the Christ to die. Pilate found no fault in the one who claimed to be the Son of God and did not mock His response. And had not the unrighteous leaders below—people of the living God—ordered His crucifixion, Pilate would have let the son of Joseph go.
Why?
"Wherefore, as I said unto you, it must needs be expedient that Christ—for in the last night the angel spake unto me that this should be his name—should come among the Jews, among those who are the more wicked part of the world; and they shall crucify him—for thus it behooveth our God, and there is none other nation on earth that would crucify their God.
For should the mighty miracles be wrought among other nations they would repent, and know that he be their God" (Book of Mormon, 2 Nephi 10:3-4).
Although the Romans exercised barbaric practices, as a Pagan society, their beliefs extended past more than one god. To hear a man say he was the Son of God would have been no different than if a man had come to them proclaiming to be a demi-god like Heracles. They would have seen his miracles and have believed. Listening to such a man would not have been against their beliefs. But it was to the Jews that Jesus needed to go.
And so, unable to be anything more than a puppet of the people, despite believing in Jesus Christ's declaration that He was the Son of God, Pilate had to listen to the people crying out "Crucify Him, Crucify Him" and then washed his hands of it.
