Yup, Hiyori had a violent character to begin with, this is shown in the 100 years ago flashback. The personality of a lot of female characters in Bleach is defined by their bad habits: abusive, submissive, lewd etc. Sure, there are "positive" exceptions like Yoruichi, Rukia (although she tends to be a bit abusive when it comes to Ichigo) and Karin, but most of the others are psycho in one way or the other.
