In "A Rose for Emily" by Faulkner, what are some of the protagonist's character traits and how do these change through the short story?

The protagonist of "A Rose for Emily" by William Faulkner is Miss Emily Grierson. She is a representative of the upper classes of the Old (antebellum) South who is now living in a rapidly changing New South. 

Miss Emily's father considered himself a member of the local aristocracy and owned an elegant house with servants, but did not really have enough money to maintain his social pretensions. When we first encounter her in the story, the neighborhood around her house has become a derelict industrial area and she herself has become too poor to afford her property taxes. She has lost her youthful attractiveness and not only has gained weight, but uses a cane. Nonetheless, she still carries some of the arrogance and sense of entitlement of the old southern upper classes and has a certain stubborn dignity in her reduced circumstances, winning battles over taxes and the mysterious smell. 

The narrator then recalls her as a slender attractive young woman in the shadow of her father, who considered her too good for potential suitors. In the story about her jilting by Homer and the ending of the story, we get a sense of how she negotiates her dual traits as a passive woman in a patriarchal society and a member of the upper classes. Although she cannot prevent herself from being jilted, she can successfully murder the man who did the jilting and control him in death in a way she could not in life.
