Judas Iscariot was one of Jesus' twelve disciples. He betrayed Jesus for thirty pieces of silver. Contrary to popular belief, the bible does not say whether or not Judas sold Jesus out because he did not fit in with Judas' plans for a military uprising against Rome. There is an alternate theory, yet to be disproven that Jesus asked Judas to point him out to the Romans. Today, a Judas is one who sells out the origianal Idea.
