Cinder can't be redeemed logically at this point. She indulges too much in her evil deeds. Redemption often comes to those who have done evil despite the fact that it's wrong, not to those who have done evil because it's wrong. Cinder is evil because she likes it. Not like Vader who does it out of pain, not like the Grinch who does it out of jealousy and loneliness, and not like Locus who does it because he's following orders.

Cinder enjoys killing, torturing, and otherwise causing pain because she's a psychopath. Everything in the show has strongly indicated this. Psychopaths are incapable of empathy, relating to people, or otherwise feeling emotions. That's what Cinder is. And that kind of person can't be redeemed. Not because the story doesn't allow for it, but because they lack the psychological equipment necessary to feel sorry for their actions.
