It depends how you "roleplay" your V I guess
Sometimes my V only kills as a last resort when there is no choice. So she spared these two dudes and the maelstromers who guarded the building. Because afterall, she's only paid to find the BD, not to murder anyone. In the same way, she delivered all the targets alive to the fixers and prefered to knock out people who on her way. The fate that the fixers have for them after, is not her concern. She completed jobs without drawing unnecessary blood (when possible).
But sometimes, another V is way more ruthless, she does not ask herself questions and kills everything that moves without remors, nor pity (did they deserve to die? She don't care, they were between her and her objective... it's sufficient to deserve it)
