He probably didn't care much what happened after he was hanged.
Actually he cared a great deal. One of the charming parts of the sentence was that he was hanged by the dangle and strangle method until he was mostly unconscious, cut down, revived, then bound to a table where he had his intestines ripped out and was emasculated. The quartering part was probably one that didn’t mater too much to the subject, since the drawing would pretty well kill him.
