Pony POV Series Dark World, the truth about Fluttercruel/Odyne

I imagine Nightmare Eclipse, being the Game Master of the Dark World timeline of Pony POV, made sure that Fluttercruel/Odyne turned out as horrible as possible. And roadblock any attempts to reform her.

Why would Nightmare Eclipse do such a thing? ... Because 1, they already had Flutternice, who was constantly fed contrary feedback by her mother and aunties.
And 2, same reason that one fanfic had Discord take a Starlight Glimmer from the past BEFORE she reformed, so he could torture her forever for hurting Fluttershy without disrupting the timeline. Nightmare Eclipse didn't WANT Odyne reformed, she WANTED her to be as abominable as possible so she could feel all the more satisfaction at killing her over and over and over.
