I can think of one strong argument for the Blades (although I don't agree with it): Paarthurnax decided to switch sides, going from terrorizing mankind to helping mankind. Since Paarthurnax may be around forever, he may always at some point decide to do harm again. The Blades mistrust dragons and will always be suspicious of what he does next. Their all-easy resolution is to kill all dragons, "just to be sure", probably sugarcoating it with stories of vengeance and duty. The people of Nirn seem to like to kill off whatever they fear, so they can sleep again at night and not worry about it anymore.

As for the Dragonborn's Thu'um being the greatest. The Dragonborn is not immortal. When they die of old age, some dragon will be the new top-dog.

I regret there wasn't a counter-quest to turn the Blades in with the Aldmeri Dominion in return for being left alone after having pissed off Elenwen earlier in the infiltration quest.
