He follows them and steals their money, only to be caught red-handed. Nevertheless, the Teacher forgives him. What is more, He invites the thief to become one of His followers and offers him a position as the group’s treasurer. Shocked by Christ’s unexpected offer, Judas decides to join the apostles, if only to figure out what is going on.

But when he fails to make them understand, he realizes that Christ’s teachings may sink into oblivion without benefiting humanity. His solution is to betray Christ. “By killing a man, have I not saved a God?”
