Continuing on in the drama they tie up Jesus. Surely they don't think Jesus is a flight risk or a physical threat to them, but I'm sure that they wanted to make a more dramatic presentation to Pilate.
Judas realizes that they are going to kill Jesus and feels remorse, gives back the money, and goes off to hang himself. I wonder what he thought that they were going to do with Jesus. But here Judas has a chance to redeem himself. To go and stand by Jesus but he is too ashamed and goes off to kill himself.
Jesus always wants to restore our relationship with God, that's kind of his whole mission here on earth, but so many times we feel that we are too far gone. That God can do nothing with us because of what we've done. Yet all Jesus wants from us is our commitment irregardless of our history. JM
