Faulkner uses the pronoun "we" in order to indict the entire town in the shameful fate of Miss Emily. They ignore her basic human needs for companionship. "We all said, "She will kill herself"; and we said it would be the best thing." This is the crux of the author's accusations of the town's lack of empathy for a fellow human being.
Faulkner also uses the pronoun "our" frequently, even beginning the story with its use: "When Miss Emily died, our whole town went to her funeral," the narrator recalls. One would think initially that this indicated coherence and caring, but what follows is hardly the case.
