In "A Good Man is Hard to Find" by Flannery O'Connor, what would be the "grotesque" element of this story?
The Misfit himself is a grotesque character--a bloodthirsty, murdering sociopath of the worst kind, who enjoys committing the deed. But the most grotesque part of the story comes at the end, when The Misfit's partners take Bailey, his wife and their children into the woods and shoots them, one by one. The killings are unnecessary, since the family has wrecked their car on a dirt road in a rural area. The murder of the two children--unlikable though they may be--is a terrible crime, and allowing the grandmother to hear the shots must have been awful for the equally unlikable old lady. The final death, that of the grandmother while on her knees at the hands of The Misfit, comes after she has tried to befriend and forgive him--another unforgivable act by a monstrous human with an entirely appropriate name.
