The gospel of Judas wasn't written by Judas, or by any of Christ's disciples. just like the other gnostic documents, it was written by people who didn't know Jesus, pysically or spiritually. The author of that piece of tripe would not have any idea if the relationship between Jesus and Judas was anything other than what the canonical gospels said.
Just more nonsense from those who eagerly embrace anything that contradicts the Bible, no matter how ridiculous or easily disproved.
