I saw a comment earlier about how this is a failure of a vibe check. She regressed her character ignored openings to get help from everyone she attempted to murder every one of the main characters. And then she just gets forgiven and all is well no no fuck that if she doesn't at least go to prison and at least extensive mental therapy it will be hard to forgive.
Do I want her to suffer the consequences of her actions through death yes but if that's not going to happen (it would have made her character better if she committed to the whole I'm a villain now thing) then she needs a extreme amount of punishment just like all the other rehabilitated villains have gotten in the story
