If you're wondering about my theory on LeFou being the real main villain of the film, here's a full theory on it:
LeFou is considered as the film's "secondary antagonist". But If you look closely in every scene with him and gaston, you'll notice that LeFou is fed up being Gaston's bad manners. In the Castle War scene, LeFou wanted to kill Lumiere, and followed by his malevolent laugh, it might mean that "he is the one behind it all". The reason I think that LeFou is responsible for all "Beauty and The Beast" animated films is that he might be part of a secret society that no one has ever heard about. In regards of the character "Forte", it is very possible that he could represent LeFou's power and that the enchanted organ was built by him, presumably hinting that LeFou is a genius, if not, a smarter one that Maurice himself. Despite being Gaston's sidekick, he was possibly hiding the plan to kill the beast for himself. That's why you never see his true nature in the films.
In the rest of the movies, its events are being probably led up and plotted by LeFou in the first place. And maybe he might plan to secretly clone Gaston as his sidekick for once.
So there you have it. My Beauty and The Beast theory.
