Is elfin bondage morally justified, or is it as evil as the human institution of slavery? Rowling shows Hermione as a crusader, as an abolitionist. Yet as narrator Rowling does not interject a moral judgment. The reader is left to decide whether Hermione's cause has great merit, is half-cocked, or is somewhere in between.
