Stone's point is that it's easy for a starry-eyed newbie to think, or be persuaded, that such sociopathic behaviour is the mark of a "True Dominate" (spelling intended). Plenty of fantasy Doms (e.g. the heroes of lots of stories on the Library, including some I've written,) are sociopaths by real life standards. (In the same way that most action-adventure heroes are.) This is a reality checklist.
