Look, no ever said Sunset Shimmer was a 'nice girl'.



She beats the crap out of people, more than she has to. Some of them are still in the hospital.



She's had idiot nobles who like to talk big to her, so she taught them a lesson, and they never bothered her again.



If she finds an ancient spellbook and the spells in it are worthless, she makes it a policy to burn it.
