"A Good Man is Hard to FInd" is creepier the second time

"A Good Man is Hard to Find" by Flannery O'Conner was very disturbing for me to read, but I found it to be even more so the second time I read it.  I think this happened because the first time around, there were a few things mentioned that I though were a little off, but the second time through, they hold intense moments of foreshadowing what was to come at the end of the piece.   For instance, it is mentioned that "they left Atlanta at eight forty-five with the mileage on the car at 55890" (617).  The first time, I thought this sounded like a police report sort of way to write out details.  Then I read that it was the grandmother who wrote this information down (617) and just kept reading, thinking it was odd and that maybe something bad was going to happen.  But after I knew what actually happens at the end- it really was a crime report!  That was creepy because it was like the grandmother was writing the future, and she was the one to suggest the path that was dangerous, so the irony is there as well as foreshadowing.  Also, it is mentioned that the grandmother thinks " in case of an accident, anyone seeing her dead on the highway would know at once she was a lady" because of the 'feminine'  way she was dressed (617).  At first, I read this as the woman being vain and the stereotype of an old-fashioned lady who always wanted to keep up her appearances.  The second time- foreshadowing! In a really gruesome way, too. 
In another thought, I strongly disliked the characters.  The older children are rude, and make stuck-up remarks about things like Tennessee being "' a hillbilly dumping ground"' and that the girl "'wouldn't live in a broken-down place like this [the restaurant/house] for a million bucks!"' (619).  Snobby!  The author did a good job of portraying these kids as mean through use of their dialogue. I also do not appreciate the grandmother's actions.  She seems selfish and unreliable by the end of the story.  At first, I thought she may be a nice person, one who even amidst a rude family still wanted to do things like tell stories and make jokes (as on 618).  But when the criminals catch them, the woman really seems to just look out for herself instead of trying to save her family (though such a horrible situation, who knows how one would react).  The woman pleads with the terrible man, that he is "a good man" and so on and shouldn't kill her (623).  Through use of dialogue, the author, rather than portraying the woman as cunning in her attempts to escape death, shows the woman to be frantic.  I think this sense comes from the repetition often occurring in the woman's speech (623-626).  The end was confusing to me.  I hated the criminals, and it disturbs me to think about them too much, because the ring-leader is too weird in the things he says- it was ambiguous and creepy (623-627).  The whole story was overall very disturbing.
