Don't try too hard here there is a lot of hypocrisy about Wanda. her that she is completely innocent since she was possessed by the lifeforce. And you see how they justify the atrocious actions of Jean for example, Scott or any other mutant corrupted by the phoenix force. And they give the green light to sadistic killers like Magneto Sinister or Selene lol WTF ...
Wanda still possessed it was not even her intention to murder anyone she wanted to eliminate the gene x in her madness so she would solve everything. if some died due to some rare circumstances but how was she going to know it being crazy and possessed, besides the direct culprit of those three words was Magneto and they are very good to ignore that.
Also as if it were not true that the largest number of mutants would prefer to be normal humans before mutants. and there are hundreds of stories about it, not all mutations are pretty and the Arakis are living proof of that, them and the Morlocks.
