Moll’s behavior doesn’t really reflect true respect for the lady, illustrating the deterioration of Moll’s morals. Before having sex with the older brother, Moll was of superior moral standing, but her morals go steadily downhill from the moment she loses her virginity. Here, Moll deceives the lady to serve her own interests. Whether the sex itself is immoral is debatable; however, the behavior the sex leads Moll to is certainly immoral, which reinforces Defoe’s point that virtuous readers can learn what
not to do by studying Moll’s story.
