While Rainbow Factory fan fiction may have been interesting for some people, and there is a place for grimdark stories. I am not going that route with my MLP fan fiction. The idea of Rainbow Dash becoming a killer scares me. But more than that, I don't see a plausible scenario where she would try to wipe out weak Ponies, given that she was disgusted with Lightning Dust's reckless actions of creating unnecessarily lethal situations, plus in the show Rainbow Dash was protective of Cutie Mark Crusaders, like in episode Sleepless in Ponyville.
