"A Good Man Is Hard To Find"

The ending to this story really threw me off.  In fact, it is safe to say that I had no idea the ending was going to unfold as it did.  When the car accident happened I know that the story was going to shift dramatically, but I had no idea that it was going to end as it did.  I found the character of the Grandmother quite exasperating and quite frankly annoying, but after the reading the entirety of story, I realized that her role in the story was pivotal and important.  I think the overall meaning of this story was that the author was trying to get across the idea that because of Man's broken condition it can be easy for humans to start going down the wrong road, and once an individual starts down that road it is very hard to turn back.
