She understands that being an exorcist is part of her "karma," and doesn't attack youkai just to make them bend to her will, but to keep a balance between the human and youkai world. In chapter 84.1 Special 17, it is mentioned by some ayakashi hoping to be her shiki that she hates men, which is why they took on female appearances.
