On a side note: were you one of the staunch Loghain supporters on the BSN? Seems like I remember the name from there. ›››
I think that's a very simplistic interpretation.
As Thomas Hobbes argues, a functional state needs a Leviathan. A sole monopolizer of power, whether be it individual, state or political organ, in order to establish order and stability in said polity. In these times, the establishment of a strong dynasty with strong monarchs was the most possible recourse.
Indeed, Redania fell apart after Visimir's death, most likely engineered by Eilhart, and the country nearly collapsed in civil war. It is that lesson that Radovid took to heart. For the stability of his country, he needed to become the Leviathan. And for him to do that, no one can ever be his equal.
There is definitely anger in Radovid towards Philippa. Afterall, she was most likely responsible for his father's death and she tried to manipulate him and use him as a tool. Inadequacy however is hard to have when Radovid outplayed her so utterly. He forced her to flee Redania, desperately try to go out of her way and create a state to control, and then defeated her at Loc Muinne and handed the Lodge a pretty big loss. Radovid has no reason to feel inadequate in front of Philippa when he outplayed her utterly. He even throws a backhanded compliment at her, telling her that part of his success was thanks to her teachings.
But there is another element to Radovid's policy. It's to establish himself as the sole bearer of power, to impose order in Redania that almost lost it without a leviathan. A sovereign monarch cannot be so if his order will not be executed without Eilhart's consent. That would make her the real ruler and not him. Him wanting to impose himself as ruler, when he is clearly capable, doesn't mean he is spoiled. It means he is ambitious and doesn't accept submission for himself, something that Philippa of all people would admire.
One only needs to look at Saskia. Saskia openly welcomed Philippa, put her in her Council and had her as her closest advisor. And then what happened? Obviously, Philippa tried to control her.
Radovid is not a fool. Philippa can NEVER be an advisor, she is way too powerful and intelligent to relegate herself to just being an advisor. Radovid knows this and she knows this. He dealt with her exactly like Philippa would have dealt with him.
Trying to make this into a black and white issue is completely missing the point and over-simplifying it to insulting levels. The reality is simple., You can't fit two swords in one scabbard. Radovid and Philippa are both too strong, too intelligent and too ambitious to coexist. One of them had to go. Radovid smartly struck the first move.
If you feel that Philippa fell at the hands of a spoiled brat, then you are thinking less of her.
And yes, that's me.
