The title of the story and the context of it go hand in hand. The grandmother is referring to society as a whole, but in the story it applies to both her son and the misfit. Her son wouldn't listen to her when she suggested he take the kids to Tennessee instead of Florida due to the escaped murdered heading towards Florida. He didn't even really take it into consideration. Personally whenever my mother suggests something, i strongly take it into consideration because mothers usually know whats best/are right. Her son wasn't turning out to be what she had hoped, "a good man".
The misfit obviously wasn't a good man, being a murderer and all. Although she did try to convince him that he was in order to save herself from being murdered. She was so upset with the newer generation not being what it used to, but here she was trying to convince a murderer he was a good man. The story could be interpreted in many ways.
