In my opinion, it is too much of a danger. Blades can't destroy cities as easily as a dragon. It's a necessary evil. It would be cool if dragon could actually destroy the cities in this game, all they can do is kill a couple of npcs which is annoying.

Paarthurnax is the least threatening and most trustworthy, in addition to helping the protagonist (more than blades) he allows to meditate on words of power.

Plus it's not like you can actually eliminate all dragons in Skyrim even if you wanted to.

The only reason to kill Paarthurnaxis is getting access to blades generic dragon hunting quests and recruitment option for some npcs.
