My surprise is that when Jesus told the disciples that "someone" would betray Him, they had no idea who this possibly could be! They didn't even have a good guess.
Judas did a spectacular job living a double life, a compromised life. By the time the big betrayal came down the road, he'd made many many micro-betrayal to ease that decision. We can learn from Judas' masterclass in what NOT to do.
