Oh Davos won't kill it. Not weakened and pitiful, exhausted by the efforts of the many against its battered and bruised form. 

To kill it in a hunt where his will and cunning are put to the test, that is to claim the head of a beast. Toppling such a pristine form of brutish ingenuity from the mountaintop where it has made its perch as an apex. That is a glorious end for worthy beings. 

But here on the sand of its home, ringed by bloodthirsty savages.. that is a mercy killing at best.
