Jesus was a good salesman according to the story
In any case; I have a hard time to believe it was not intentionally what Judas did to Jesus (conspiracy), in that meaning I think he knew what would happen. The whole story seems like a setup, a mind trick on the crowd, when Jesus point out Judas as the betrayer and thereafter sacrifice himself.
For some reason I always think of the explanation of why Harald Bltand (Bluetooth) (the Danish King that converted the Danish people from Asatru to Christianity); The priest Poppo "proved" the truth of Christianity by wearing ordeal; he stuck his hand into an iron glove, which was heated, so it was glowing, without the hand was damaged. That evidence yielded Harald and he was baptized.
This is hardly truth and he probably converted to Christianity because of its influence across Europe, which made it a secure decision for the country to adopt Christianity. In other words; fabricated tale.
The same goes for the story of Jesus and Judas, probably.
