I'm less optimistic, because I think one reason they ended the show the way they did is that they wanted to leave it ambiguous whether Wanda will become a hero or antagonist (she'll probably never be a full-fledged villain, but she doesn't have to be). That's one reason they didn't give her an "out" to make her less guilty for what happened to Westview, so we'll end the show not knowing for sure what lesson she's going to learn from all this.
So the final scene has her studying the Darkhold, and that could be a good thing, because it's the only known source of information on the powers of the Scarlet Witch, but it could also be a bad thing, because it's dark magic and Agatha was corrupted by it. She might break the rules again to get her children back, which would put her at odds with Strange, or she could team up with him, or both. We don't know if Westview has taught her that this kind of magic is wrong, or just that she screwed up and now she has the chance to do it right.
I'm not predicting which way they'll take her, but I do think they want to end the show in a way that suggests she's not an unambiguous hero. Hopefully this is the start of her journey to being a better person, but whether it is or not, they don't want us to know yet.
