Well, here one; kind of cheesy, but whatever.
Setting: Generic Medieval Fantasy
Having been born into a life of petty crime, she is offered a way out as the apprentice of a wayward wizard, however, he is cut off from his magic by a priesthood of the goddess of magic due violating several of the rules they had set. After this, he becomes depressive, and more or less refuses to act like himself. After attempts to comfort him fail, she sets off to attempt to murder the entire clergy, and eventually, the goddess herself.
Possible eventual conclusion involves the goddess herself being sorry about the actions of her underlings, as she was unaware of what they were doing and offering to restore the connection. Response being "I'm not here for his sake, I'm here because you hurt me."
