At the time Jesus promised Judas that he will be one of the twelve disciples sitting on thrones judging the twelve tribes of Israel, he had no idea that Judas would end up betraying him. That clearly proves that Jesus had no idea that Judas would betray him. It just proves that Jesus was not aware of the unknown so he couldn't be God knowing everything from the beginning. Jesus was a con man. The dudes who followed him pretty much satisfy his craving for attention so he made promises to them so they feel special. One of those that he made empty promises to was Judas. Jesus was an empty vessel who never accomplished anything in life because he chose to just goof off with his compadres.
