They failed the Empire, they failed to protect the septim line, and they lost against the Aldmeri dominion, they are in no position to be giving out orders acting like their the Dark Brotherhood, and those hermits make much more sense to me,
Without Paathunax's help, you can't stop Aldiun and i bet plenty of blades were former criminals, the 2 player characters from Morrowind and Oblivion for a start, and if your biased, you can't know who is right, due the fact you've admitted you're biased.
Hehe, I agree here. You know, I had a lot respect for the Blades in the old TES games. But this was just bizarre. But then, I am always a friend of "give 2nd chances", and that includes Dragons. It was just lame that you can summon Odahviing only after the end of the main quest, when it kinda superfluous.
