In "A Rose for Emily," do you think Emily become more human after her father dies?
Your original question asked more than one question - I have had to edit it down to one because of enotes regulations. Well, the short answer to your question is that the text tells us the townspeople at least thought that the death of Miss Emily's father made her more human:
When her father died, it got about that the house was all that was left to her; and in a way, people were glad. At last they could pity Miss Emily. Being left alone, and a pauper, she had become humanised. Now she too would know the old thrill and the old despair of a penny more or less.
According to the townspeople, then, from their perspective, the death of Miss Emily and her poverty removes her from the high position that she once possessed and allows other folk to sympathise with her. It makes her more human, as she is struggling with the kind of problems that the rest of the townsfolk struggle with as well.
