Yeah, I don't buy that.
It's true that in chapter one, her mom explains that the father died of a disease, but the next line makes it even more strange...
here's the page:
the "after that, she wanted to become stronger"... why the hell would she want to become stronger like that if her father just succumbed to a malady.
You don't become this obsessed to commit genocide just because your father died of natural causes...
If she really just wanted to stop being a burden on her mother, there's tons of other ways to do it.
Certainly better ways than go fight the strongest being in the world. I don't know about her mom specifically, but most mothers would feel much more burdened from asking herself if their kid will come back alive...
