As villainous as she is, I do have to wonder; How on earth was she not queen?! ( I get the whole monarchy system, but) seriously, a villainous strategy like this would win wars, rule kingdoms effectively. especially if this girl knows how to string hearts towards a different direction.
On a neutral standpoint, regardless of which side, tactical approaches like this is worthy of a crown. But motive is the truest sense of what makes them villainous or righteous.
