No what I meant by the example from "the one within the Villainess" was that the Charm itself only makes the Victim think Positive of the one who charmed them! It does not control any other actions. Even if the Charmer demands you KILL someone you care for. You won't do it unless you WANTED to do so yourself! So say you got charmed and they told you to kill someone you were already going to kill BEFORE the charm..Not "you might have, YOU WERE!" then you would do so in a "no need to tell me twice!"
The Reverse harem in that can't use the excuse of mind control to justify their actions! I can see though that yeah you COULD make a case because at the end of the story when she delivered the Karma, she first made SURE what was left of the Charm in them was dispelled because while it didn't mind control them, it DOES allow them an easy escape from blame (By loving the fake heroine, they can convince themselves they weren't in control of their actions, which they WERE, no partial, they WERE! The Charm was just a convince to escape responsibility and if they have to, push the blame onto the Fake Heroine
Then again it's still a TRY! I can see your point because of a story I read that manga name I forgot, but basically the FMC was condemned as a Villainess, you know the spiegal with the add that her MOTHER was being punished with her under the excuse that she wasn't her father's child and her mother cucked him! Later when the story starts proper when she's getting her life on track, one of the "Fish's" her childhood friend who helped in ruining her found her as the Kingdom she and her mother were forced to flee to was his! And he apologized for what he helped do! He broke free when he like the rest of the fishes became INSANLY CLINGY to her Half-Sister that he killed another man in a duel and was exiled, away from her and the Charmer (FMC father's second wife, the mother of said half-sister though the story HEAVILY implies she's just some pretty orphan girl she took under her wing and charmed FMC father into thinking was his child from a one night stand in order to get into the family, she is the REAL villain of the story) he is able to remember and so remembers all the terrible things he did and said, ESPECIALLY to FMC (As said, she was her father's daughter, false evidence and testimony was used to frame her and her mother to exile them, hell a point is made that FMC is also a witch like the Charmer, but the woman assumed without a teacher and now alone and abandoned, she'd die off somewhere! While it wouldn't matter to the Charmed, it was more to trick the people into thinking FMC and her mother were villains, as said the Charmer was hoping they'd die or suffer a bad end being two vulnerable women out in the wilds, who knows who might try to go at them! Still stupid of her to assume without confirmation!)
The story kind of has FMC go HARD on all the Charmed, holding them ESPECIALLY her childhood friend to account for what they did charmed even when told the details, though the fact she marries him (he's the ML) at the end kind of feels like the writer realized TOO LATE having the FMC be so unforgiving to mind control victims had her eventually change her mind and makes it more "she was hurting, after all she lost her home, her reputation, framed for something she didn't do, reduced to a commoner, have to take care of her mother who herself lost her mind and is so depressed, she partially blames FMC for their exile and woes. Just to be told "it was all mind control" must have set her off! She's pretty forgiving to her EX Half-sister as the story makes it clear she has NO POWERS, she was simply just a "smokescreen" by the Charmer and was basically a regular girl with no powers
