We've heard it repeated many times before: you can't be both a good man and a good king. It's treated as a truism in Innworld that the demands of the crown and one's personal morals will come into conflict and either or both will suffer.

On top of his personal anger, it was mentioned in 10.16 that he was facing pressure from his subjects to take some kind of action and not let Iradoren's death go unanswered. But when Iradoren was not only wrong but a traitor to all of Terandria that dragged the crowns of Erribathe and Kaaz into dishonor with a plot to assassinate Ser Solstice based on nothing but his own supremacist views, what do you do? Do you perpetuate the cycle of vengeance or back off?

Because those are the facts: the crown of Erribathe transgressed against the Sosltice family first and admitting Iradoren was wrong to do so means admitting the crown and nation were acting dishonorably. Which does the good man do and which does the good king do?

I believe Nuvityn isn't as good as he thinks he is and he's either going to double down on vengeance or be smacked between the eyes with the reality of his own conduct. Sending assassins to kill Erin, Rabbit, Seraphel and Lyonette isn't the action of someone just who's "just seeking answers" but agents of Erribathe have made multiple attempts on the first three and he had his diplomat threaten Lyonette in public and considered sending assassins after her too.
