Barabbas: the Jesus of Liberation Theology?

It occurred to me the other day, comparing Jesus bar-Abbas and Jesus bar-Joseph that Barabbas is far more akin to the Jesus of Liberation Theology than is the historical Jesus of Nazareth. After all, Jesus Barabbas was a man of the common people, popular with the crowds. He understood their situation and the reality of their oppression. He exercised a preferrential option for the poor and oppressed by getting involved in a revolt against Rome. He sought to change corrupt systems by taking prophetic action against sinful institutions. He was even willing to put his life on the line for the people and the cause he believed in.
