We know precious little of the man called Barabbas, a contemporary of Jesus of Nazareth. He is variously described in the historical record as thief, murderer, rebel, and notable Roman prisoner.
His release by the Roman Prefect Pontius Pilate was part of the supernatural plan for the Christ to offer himself as the ultimate blood sacrifice, but it's doubtful Barabbas understood any of that at the time.
Many have wondered what became of him, or rather, who he became after that fateful day. Someday we will know the answer, but in the meantime, we can imagine that, like all of us, he too sought a path of personal redemption, imperfectly.
