DragonGirl has a point: Killing Parthuny won't grant you much besides a Dragon Soul, Bones and Scales. You also get a semblance of combat bonus against other Dragons via Esbern.

However, the Blades in Skyrim are doing exactly what they were initially built for: hunting dragonkind. They're honouring their Akaviri Dragonguard roots.
