<p>the "evil knight" is a well-enough known archetype that it can stay as its own category.. it also makes it much simpler, since it can mean both a military rank or a simple title.. if we really, really want to get rid of it the best would be Aristocrats (for those who are of "noble" rank (barons, lords, knights, counts etc) - without being Monarchy (kings, queens, emperors, princes, princesses etc) ).
