Sam or Dean seek vengeance or destroy the world if the other one is killed

I'm looking for stories where it is either an outsider or the impersonal 3rd person narrative that comments on the destruction or vengeance Sam or Dean will wrought if the other is killed. I guess implied in that is also what they will do to get the other back

Flesh, Blood, Bone: "After Jake kills Sam, Dean has nothing left. And there is nothing more dangerous than a man with nothing to lose."
Not really destruction on a "destroy the world" scale, but Dean does go pretty dark here
