i thought judas wrote the book himself,apparently it is somebody else.

National Geographic said the author of the gospel of Judas believed that Judas Iscariot alone understood the true significance of Christ's teachings.http://english.aljazeera.net/NR/exeres/A641817E-B5C1-48C6-9960-1FA06AB27654.htm

If Jesus existed, it's his teachings that make him one of the world's greatest teachers, not human sacrifice (which as I've said before was no sacrifice at all if he was a god).
