Since I've loads of free time, I decided to make my own research on miscellaneous historical events. Sorting them and reassembled pieces of misinterpreted facts. It is only an amatuer research done by an 18 year old so it's up to you if you want to make sense of it....
First thing first: to my kind commenter Aput, there s no such person as Jesus Barabbas. You might have mistaken the word Barnabas which is the Gospel that had the story of Jesus's crucification.
Another fresh and shocking fact: The Gospel of Judas was just recovered last year and was restored this year, having 85% of its original content. (watch Discovery Channel lately?)
Muslims believed that Judas was the person crucified based on the Gospel of Barnabas. The Church denied Gospel of Barnabas's credibility, and was labelled as a product of forgery.
The new found Gospel of Judas has the story of Jesus's life, similar to the rest of the disciple's gospel but does not have the story of Jesus's crucification. It ends abruptly at the part where Jesus was supposedly caught. Why so? Logically, Judas was not present during the crucification! He was simply crucified.
The famous kiss given by Judas was therefore not an act of moral grotesque but simply a gesture of thanks from Jesus to Judas. Booyah!
Any transformation that had taken place: NO! Judas, to start off has a striking resemblance to Jesus. It was told in all the discples' Gospels that Judas features are similar to Jesus's and had many times confused Mary, Jesus's mother.
So that's that. Erm, yes... this is only an amatuer study and if I dissapear from this world in an abrupt manner, you have the church to blame. --just a playful disclaimer--
There're more I would like to discuss concerning the Last Supper painting particularly about MARY MAGDALENE, but I'll save that for later...
