I believe that the short story “A Good Man is Hard to Find” by Flannery O’Connor is really telling the story of how hard it is to change one’s way of thinking.
In the story, one of the main characters, the Grandmother is a beyond shallow, ignorant and judgmental, selfish woman. She remains that way even when coming face to face with death itself. She looks a convicted felon, whose crimes she is aware of, and believes that he is still inherently good solely based on his noble background. Even after the Misfit orders the death of her own son, daughter in law and grandchildren, she still insists on him being good. Her faulty outlook on the world is so deeply implemented, that not even a situation so stressful can overrule it. Not even the possibility of death can turn her into a “good” or at least “better” person.
