Violence is a much more common aspect of life in Eorzea than it is in the modern world. Life's value simply isn't held as high: many people have most likely lost family and friends from any number of causes ranging from disease and starvation especially in the wake of the calamity), to violence and war.
Adventurer's especially live on that cutting edge. That doesn't mean that their hardening has no effect upon them, or that the act itself should be taken lightly.
My own observation to contribute is that PCs often do not bat an eye, whatsoever, at the mass slaughter of nameless faceless NPCs. They'll obliterate any number of guards, soldiers, bandits, and so on without a second thought (and while happily basking in the glory). But the moment one of those NPCs has a face, a name, and a sentiment that is not pure hostility, then suddenly the awful face of death's reality stares them directly in the eye.
As a personal note, the issue definitely is relevant to Aya in a number of ways.
