The term 'Double-Crossing Disciple' refers to JUDAS, a disciple of Jesus who betrayed him. JUDAS was one of the twelve apostles chosen by Jesus to spread his teachings and help him in his mission. He was the one who ultimately betrayed Jesus by handing him over to the authorities for crucifixion. His betrayal is seen as a great act of treachery and is remembered in the Christian tradition as an example of the consequences of double-crossing.
