I think that Cinder has motivations that can't be discerned just yet due to her secretive nature, although presumably, it evidently has something to do with Beacon, so she might have a vendetta against the academy for unknown reasons, or a particular individual there. In episode 8, there was a map that led straight to Beacon, and here, she's infiltrated the school, clearly indicating whatever she intends on doing, it involves the school.
