I'm not entirely sure about this, seriously. However, I DO know that Lucifer, God, Death, and the rest of the horsemen can't be killed with it.

Reason 1: Lucifer didn't die when Dean used it and shot him, and then he admitted it can't kill him, which was proven earlier.

Reason 2: God is the ruler, possess primary, condescending, unquestionable authority, you get the gist. He can't be fully and utterly indestructible.

Reason 3: Death is like so much, that it can't kill him, either.
