It's used often as a twist ending and the problem with that is that it's usually a fairly foreseeable one unless the narrator is unreliable (which I think is generally frowned upon here). That being said, some of the best pastas I've seen have the narrator as the villain and establish this fact from the beginning, so that can work.
