Are you sure? But that's sort of missing the joke about this demon. It's dark humour, I admit, but it's there.
Namely, that for all that it's mean and cruel, it's actually pretty harmless compared to most 2nd Circles. If it gets into Creation, it's going to act like the Devil in folklore and make people's horses go lame and steal old women's teeth. And for a sorcerer, it's a wonderful, wonderful Second Circle to summon. It barely fights task-binding if it likes the sound of the task, it's good at what it does and it has a clear and well-defined purpose. For a sorcerer who wants to do something like steal a crown off a king or sneakily replace someone's valuable tome of sorcery with a fake which has the spells all subtly wrong, it's incredibly useful.
So, sure, you can get all outraged about her, but really? Most sorcerers are going to consider her a mix of a minor annoyance and a very useful asset.
