Norfolk survived. He was in prison under sentence of death and Henry died with literally a day to spare. His son had already been executed. Norfolk stayed in prison for ages and IIRC was released by Mary.
He definitely had sympathy with the old religion. He was very anti the dissolution but was a loyal enough servant of the crown to be in charge of putting down the Pilgrimage of Grace. That conflict is why I find him so fascinating.
Again, do you think Norfolk made Mary Boleyn into the king's mistress? Or did it happen regardless? What do we know of his actions that early on that suggest he had a hand in it?
NB I am not pro-Norfolk. He was indeed a schemer, and also a rather vile domestic abuser. I am kind of a sucker for his dry humour though. You can read a lot of his letters to the King and Cromwell at british-history.ac.uk and they make me laugh.
