Wander's familiar with death. She grew up in Ul'dah and survived via petty theft, so she's seen plenty of friends and acquaintances get hurt or die in that line of work. However, in a way, I think living in the city sheltered her from actually having to do anything. Ul'dah, while dangerous, is relatively stable compared to fringe villages where one might have to hunt for their own food or fend off beast/men. Even if it came down to her vs another, I don't think she'd do it. If she were capable of killing, I think she'd have done it by now, considering she has a foot in the water already as a professional thief.
