It is a dumb and over-used idea in other forms of fiction that either has little to no consequence, or the writers make so big a leap in how powerful it is that the plot line behind such a character concept just falls apart on its own. When you look at how they wrote Jesse Turner (the writers claimed that him being half-ghost (which is what the demons in supernatural really were, but with more supernatural power than regular ghosts) and half human that he could destroy the angels with a word. Yet demons in terms of raw power are much weaker than angels. All in all, not only would it be ridiculous, there's no reason for that kind of thing to fit in the mythology of the show.
