From my own personal interpretation it seems to me that More really doesn't care whether the divorce goes ahead, and he does his best not to portray himself as a Martyr. More knows that there is no way that he will be able to sway the Kings opinion and it would be against his own morals to try and do so, but as an alternative, More can control that that part inside that is his conscience. More does not wish to change the world with his beliefs and convictions because to do so would contradictory. He merely wished to know that he had stayed true to himself and he thought this could be done just by staying silent. Yet More was so well renowned that his opinion had to be made public. More merely wanted to live his life knowing that he had stayed true to his conscience, he had no intention of being a martyr. Hence his frustration when Chapuys commended his stance against the King.
What I'd like to know is what all that hawk stooping from a cloud stuff was. it went straight over my head.
