Based on the work of Albert Schweitzer, Bart agrees that maybe what happened was that on a deeper level of betrayal, Judas spilled the beans about the Messianic secret, which tied in closely with being the "Son of God", a messianic title. Bart states: "But what do the Jewish authorities accuse Jesus of? They accuse him of calling himself the messiah (Mark 14:61-62; note: the “king of Israel” was also called “the son of God” – see 2 Sam. 7:11-14).
And that is the charge Pilate tries him on. Pilate asks him “Are you the King of the Jews,” and [...] this is the reason he had him crucified."
This makes more sense to me than the simple garden-kissing incident alone.
Another thing PARADIDOMI doesn’t mean betray?!
