The final Apostle of the original twelve: Judas Iscariot. He is forever known as the "betrayer." Why did Judas follow Jesus to begin with? Was he sincere at the beginning and then inauthentic as time went on? Why did Judas betray Jesus?

John 6:66-71 - One of You is a Devil
John 12:1-6 - Greed
Matt. 26:14-16 - Greed
John 13:2; Luke 22:3; John 13:21-30; Matthew 26:22-25 - Judas Opened His Heart to Satan, but the other Apostles still did not know at the time
Matt. 26:47-50 - Judas Betrays Jesus with a Kiss. Was he trying to force Jesus to act? Was he doing this because of unfulfilled expectations?
Matt. 27:3-10 - Tragic Ending to Judas's Life. Sin never satisfies the way we hope it will.
