I completely agree.
Shocking, I know.
I am a big fan of the tried & true idea that an individual's choices have consequences.
Now, before you begin celebrating — remember that it cuts both ways. Heroes are only heroes because they maintain a higher ethical standard than the average bear. And revenge is — well, it can be satisfying — but it's not ethical. I don't think she will be absolved. She will always be a villain in some way.
Personally, I feel she fits into the Anti-Villain role more than others.
Examples of the Anti-Villain — for those who are wondering — would be Hannibal Lecter (Silence of the Lambs), Vincent & Jules (Pulp Fiction) & Patrick Bateman (American Psycho). Make no mistake, these are not good people. They can be witty, they can even be charming. Some even have tragic origins but they are still bad people.
Another possibility is the Corrupted Villain whose examples include Michael Corleone (The Godfather Part II), Alonzo Harris (Training Day), Regan MacNeil (The Exorcist), Mrs. John Iselin (The Manchurian Candidate) & Captain Bligh (Mutiny on the Bounty). The Corrupted are often — but not always — those that were once good, but have fallen. If that is not the case, they are simply characters that are in positions of authority that should be good, but aren’t. Sometimes — in the case of Regan MacNeil — their souls are corrupted.
In short, Cinder will always be a villain in some way whether she deserves absolution or not.
As to the question about Raven, I have no idea why people aren't hunting her down. Maybe the area is too dangerous. Maybe the fans like her more. I honestly can't say. Though she definitely has more blood on her her hands than Cinder.
And someone correct me if I'm wrong — Raven saved Yang in Volume II, that's well established — but was she part of everything? I'm still not sure about that.
