She told me she was a pacifist, a vegan, and a dozen other things when I saved her from bandits. I would have ridden off without her, or just taken her to the nearest village, but she was small enough for my steed, and I needed company.
Plus she was a decent cook, at least with the plants she'd find. But slowly I introduced her to meat, and hoped that I could eventually get her to a point where she could kill if need be.
The day I needed her to save me, she couldn't kill.
But she could maim.
