If Malchediel had been told those words as he was sent off on a mission, most definitely not of his choosing, he would have laughed all the way to Earth. His intent was to do what he had been ordered to do so as to be able to return to what he really loved, what he was good at. He was a Warrior Angel, not a baby-sitter.
