The answer is: Judas Iscariot

Matthew 10:4 - Jesus would have known that Judas was going to betray him long in advance of Judas himself knowing.

Ah, Judas Iscariot! His name has become synonymous with betrayal through the ages, typically conjuring images of deceit and treachery. Interestingly, Judas was one of the twelve disciples chosen by Jesus, and that underscores a fascinating aspect of Jesus’ ministry: the inclusive nature of his compassion. He welcomed everyone—yes, even a betrayer! It's notable that even though Judas' actions were disheartening, he was part of the close-knit group—living, traveling, and sharing teachings with Jesus.

Now, while it's natural to focus on the negative aspects of Judas’ choice, think about the intention behind the moments that led to his transformation from a devotee to a traitor. The Gospels suggest a somewhat troubled soul, perhaps someone who struggled with his motivations and the overarching destiny at play. Intriguingly, the name "Iscariot" may connect back to a location or an association with a particular group, enhancing the size of his persona beyond just the act of betrayal.

What's quite engaging to consider is how other figures in the Bible wrestled with moral choices and fidelity. Just as Peter, in his moment of weakness, denied Jesus three times, Judas made a grave decision in a desperate moment. These stories echo the complexity of the human experience—choices and consequences aren’t black-and-white, and understanding them deepens our grasp on compassion and mercy.
