We may never know the true story behind the actions of Judas Iscariot - whether he handed Jesus over because of his greed, was possessed by the devil, or Jesus himself asked Judas to alert the authorities. Whether Judas was a betrayer or a best friend to Jesus is a question that can never be directly answered. What we can establish with certainty, however, is the manner in which the New Testament canon has shaped so much of what we consider truth.
