In spite of all his faults, he knows he has a lot to be proud of. But even if he believes in himself, it seems that another eclipses him in his shadow, and so what everyone else sees is a washed-up old king who’s barely holding on to the power he once had.
Everyone loves his newest rival, and yes, he calls him his rival because there’s never been someone he both loved and hated so much at the same time. Part of the problem is that he doesn’t know how to please everyone anymore, and trying his best seems to produce little to no results.
So he allows himself to be the villain to the hero, to be the darkness that highlights the day, and wonders if anyone will feel sorry for him when he dies.
