Well I do think some of her actions reveal a bit about her character. If she had a vendetta against just Beacon, why is she targeting the whole kindgom, stealing every speck of dust around, employing a corrupt orginzation, criminals, etc. all just to destroy one school and/or city? Her MO just seems a bit more.... .grandiose, than just wanting revenge against a school that took her mother away.

Then again, you are right, we don't know much. She could be petty enough to do all of that. There are plenty of villain characters who are like that. The Evil Queen for one( sorry for all the OUAT references, I just freaking loooove that show).
