Who was the most foolish ruler of all?

Freca was a fool for going to Edoras out numbered many times and insulting the king in his own house, and maybe not so in other houses, but this was Helm.
If he really thought that Helm was so blind that he could not see through his power play, and then to react with a vieled threat, when he should have laughed along with the rest and then gave a speach about peace between Dunland and Rohan, and the prosperity that such a marriage might provide both kingdoms, an end to old grievances and new trade missions that would make them rich . . .
I could have pulled it off, but then again I'm not fat, and I am more like Helm.
