I’d say take it up with Borges, but the old librarian’s dead. Oh, well… In any case, when one looks upon Judas Iscariot (the other Judas is Judas Thaddeus) in the context of this story one has to remind oneself that the Gospel is** not ** journalistic reportage. It’s a heroic retrospective of the founders of the early Christian Church, set down 40 to 60 years after the fact, largely by first-generation new Christians recounting what the surviving original founders had told them. As such many of the players have their real-person characterization overlayered with archetypes, and many of the behaviors are filtered through the particular POV of the guy from whom they heard it.
From the POV of their fellow apostles, immediately after the events, Judas plain and simply sold JC out, never mind deep psychological motivations, and JC was so great and so on-message that rather than run away from it he took it like a (Son of) Man. Soon after, Judas dies under unpleasant circumstances (either hangs himself or falls off a cliff depending on which apostle is telling the tale; maybe he hangs himself AND then the rope breaks and he drops off the cliff) so from where they were sitting, it looks like God must have had a good reason to smite him.
Apparently the fellow apostles were suspecting him of sticky fingers with the finances all along (how come Matthew Levi was not named treasurer??) so this must have made them conclude, oh, so he was really up to no good all along, the Devil must have been in him.
Now, as the narrative becomes more elaborate over the years, it turns out that JC took it like a Man because he was the only one with all the pages of the script, and the end result is the followers now have a mission even greater than any they originally imagined. Groovy, but… Judas still got smit, didn’t he? So God must still be mad at him for something… Well, as *Shodan ** put it, thispart of the story communicates that doing the wrong thing for the wrong reason is still a “wrong” even if the end result is a net good. Also, when tied together with the way that Pilate is whitewashed as being merely spineless before public opinion, rather than actively evil, it communicates a message of: "don’t join us and then * turn on us; even if all turns out for the better in the end, you will be treated more harshly for being one of us and turning on us, than if you’re merely an outsider opressing us."
(Of course, a modern writer could have had repentant Judas run up Golgotha and throw himself at the foot of the cross begging the dying Jesus for mercy, only to be killed by the soldiers the very instant JC breathes his last w/o another word, leaving us all with an eternal cliffhanger. Take it up with the authors… also dead
