1) Every single time she meets a person, she wonders how they would taste if she ate them.
1A) Yes, this includes children.

2) She was raised in a violent, racist culture that taught her that aliens were only useful as food or slaves. She has eaten sentient meat all her life and only tapered off in the last few years.

3) Her fiancé was abducted when she was sixteen, and tortured for years. When she discovered at nineteen that her parents had arranged for the abduction, it drove her insane. She killed her entire family (including her four sisters) and destroyed the family home (with some hundreds of slaves inside).

4) She sold two of her ovaries to a slave broker, and the children cultured from those organs are still being sold and eaten. Because her family was of minor royal blood, this crime made her infamous. And that infamy made her rich off of slave royalties. She literally sold herself in every way but one.
4A) She still has a valid slave seller's license and auction floor pass.
