How does Faulkner use Setting to influencethe reader's consciousness morally?

Research Paper: A rose for Emily by William Faulkner.
Paper Question: How does Faulkner use Setting to influence 1) the reader’s consciousness morally, 2) to find a symbolic comparison or contradiction with the protagonist’s actions, and 3) convey how these actions parallel with the historic events happening during the American Civil war ?
Topic: Faulkner uses “A Rose for Emily” to address themes of change and progress, especially as it relates to the American South. Although he describes particular individuals within Jefferson (Miss Emily, the older men and ladies, the town leaders), he seems to be using them as symbols for the larger issues that the South was facing at the turn of the twentieth century.
