So circiling back to what started this tangent, the argument initially presented was that Wanda was the hero because she beat up the villains.
I feel like I have demonstrated that Wanda is no more heroic in this story than any of the villains. At the end of the day its one villain beating up another, its Thanos vs Ultron if you will. Its basically a turf war.
We can argue how low Wanda got in this show, and how much her acts can be forgiven, but to call her the hero of the story is simply not true.
Also we can point to the beginning of MoM, which is several years after the events of Wandavision. Has Wanda shown any remorse, did she try to help the people she hurt in any way?.....nope, zero, zilch. If we had seen that, we could at least go with the remorseful character that becomes a hero again....but nope we don't get that either.
