What leads to Emily's tragedy from her family background, social background, and her personal characterisics in "A Rose for Emily"?

Emily is a product of her environment. She has suffered at
the hand of her overly strict father. No man she dated was good enough for Emily
according to her father. He would run the men she dated away, insisting that each one
was not good enough for his Emily.

Because her father was
too strict, Emily remains single even at thirty. She becomes withdrawn. She isolates
herself from others. Then one day, Homer Barron comes into her life. She is seen with
him in a horse and buggy on Sunday afternoons. Talk among the people is that they are to
be married.

Later in the story, Homer is not seen anymore.
The people in the community feel that he has abandoned her. It is only after her death
that they learn Emily's horrible secret. They find Homer's rotted corpse upstairs in the
honeymoon suite that Emily had prepared many years ago. What is more horrible is that
they find a iron-gray strand of Emily's hair on the pillow next to Homer's dead
body.

Obviously, Emily lost her sanity somewhere along the
way. This could be due to fact that her father would not allow her to have gentleman
callers. He was too strict. He forced Emily to become an isolated spinster. No one knows
how much she suffered behind closed doors. In her death, Emily's suffering is
over:

The
funeral is a morbid affair. Soon after Emily is buried, several of the men force the
upstairs open. There they find what is evidently the rotten corpse of Homer Barron. Even
more grotesque, they find a long strand of iron-gray hair on the pillow next to his
remains.
