This quote portrays both themes through the grandmother's use of religion to try to dissuade the misfit from killing her and the flaw in her character, which is believing she is among the best and doesn't deserve to be killed. The grandmother's use of religious morals conveys the common catholic theme in O'Connor's stories, but she also shows her obvious flaw. She begs the misfit not to kill her and she offers anything to save her life, however at this point her family is dead and she hasn't even shown the slightest bit of despair for their deaths, exposing her selfishness.
