That's a good one Chuck. You know that God knows all the story. He knows the beginning and the end. I think that Judas was just the avenue to get Him to the cross, and of course the cross was the means He chose to give His life.
We read that Judas denied Jesus for the silver, but we don't know that Jesus didn't tell him. We know that Jesus knew it, however I don't think God thought it was important for us to know that. I won't be surprised to see him in heaven, after all he might just have been doing the will of the Father.
I guess some things we will just have to wait until we are home, then we can ask God those questions. I want to know why He made fire ants, and why did the dinosaurs vanish. Being a bow hunter, that would have been a challenge!
