Everything Really the could be said to anwer your post
Rochedalaix was said well indeed by
Klinton.
I will just add my 2 cents as well, but indeed Very Well Done
Klinton.
Hero manipulation is the bread and butter of comics, everyone hero has been threw it multiple times, so Villains even are specialist in this field. Saying cause a hero has been manipulated by a villain is why they are no good in then turn has to be applied to every hero as well cause each have been down a the same Roads. It is life of the superhero, in each comic, in each universe, DC Comics just as much as Marvel and so forth.
The manipulation by a villain to explain Dissembles and HoM was also used to help save her character as well. Bendis's version tore to the very soul of who she was and completely tried to destroy her character and her history from start to finish. Manipulation by a Villain says nay and says the core of her character is fine, this in-turn then saves her from the purgatory she had been in and saved the core of her character, so in this case manipulation, like in many other stories, helps to explain greatly why the bad things happen in a clear form, especially when a character such as Wanda her whole life has been a Good Person Among Good People.
Also, the idea of True Villains is So Lost in the Wanda Argument IMO. HoM story, even after the recon was a story of tragedy and manipulation. True Villains are people who decided to do Bad things by their own free will and wants. They plot, plan and manipulate what they need and give much to little care to what others think or who gets hurt. To be a Villain in true form is that of choice and free will, it gets lost in this when it comes to Dissembles and HoM.

Finally, saying she lost her chance to be an Amazing Character is not correct in the least. As Klinton said, she always had been an amazing character, in fact why Dissembles hit so badly was that she be the LAST one anyone would believe to have been apart of it and with the recon that makes it so. Bendis had to Breakdown her Whole History to make it work, but that was a task that did not work at all cause it was sloppy and filled with holes the size of trucks! Wanda's history is that of True Heroics, Love, Training and Friendship, their are bumps yea, but nothing out of what others don't go threw. 98% of her Carrier, at the Very Least, has been heroic!
