Nope, you even misunderstood the soul split. They explicitly explained that she wasn't split in to "good" and "evil". The fractured part of her soul was just frozen in time from when she was the ranger-general, and the whole conflict from the cinematic was her having to explain(to a young and idealistic version of herself) why she made the choices she did.
And if you think they "redeemed" her, then you've REALLY misunderstood the story.
