While I have not decided to see the movie yet myself, The diccusions I have been having about the with others online have been very vocal in details on what happen and breaking it down more then enough, both the good and the bad.
By those long detialed talks, It is an Easy
YES for me not just as a fan, but as logic by what the story gave to us with that boils down to simple
Possession & Manipulation by the darkhold and by fact of history of other media that have done similiar stories over the decades. For the Record, while I am more possionte in saying this about Wanda, if this is a story ever about anyone else that had a simliar story done to them, I Logically say the very same defense of them as well.
Ad to the factor when she comes to from the Manipulation, she destroys the manipulator in all realties to save others from it. It is an example of the differnce between the true person and the demon they are made into during possession.
It is scatterd threwout MoM that the same happens to everyone(Mostly Stranges) who are effected by the Said Darkhold and have done worst with it, so it is not just a Wanda thing. But still it boils down to manipulation and possessed by the book, so any character, hero or common, effect by such is always given the road to come back and should still stand today.
To give better diccusions on this topic are bellow for further into this, but their are many more around:
