“Rabbit, Run” by John Updike (post 5): Rabbit Angstrom urges postpartum, sober, alcoholic wife to drink, to get her to have sex

When she does not do what he wants, he leaves home to be with a prostitute. His wife then gets very drunk, and accidentally drowns the baby in the bathtub.

Why do Rabbit and his wife act this way? No explanation is given, leaving the impression that they are just not very intelligent or emotionally mature.

And since the characters have no clear signs of multiple personality, the novel has little sense of psychological depth, and does not seem very literary.
