Judas was very upset that Jesus didn't do things the way he, Judas, thought they should have been done. Judas wanted a real revolution, an overthrow of the Roman power, an opportunity to allow Israel to be a power unto itself. He willingly betrayed Jesus.

I have found that my greatest disappointments are when people have not lived up to my expectations. It's not that others were bad, evil, nasty or mean. It is just that they did not do the things I had expected them to do. I like, Judas, had my own ideas, my own dreams, my own expectations. How dare others not live up to them!

Life can only exist through diversity. Allowing others to freely choose their own course of action is appropriate. Expecting others to live up to my expectations is not. Hopefully I can learn to not foist my expectations on the lives of others.

Matthew 26:14-16

    Then one of the twelve, who was called Judas Iscariot, went to the chief priests and said, "What will you give me if I betray him to you?" They paid him thirty pieces of silver.  And from that moment he began to look for an opportunity to betray him.
