Early in The Metamorphosis, we learn that Gregor wishes to quit his job and be free of his family obligations. Be careful what you wish for.
Being turned into a bug takes care of this problem for Gregor—you could say it's overkill. Gregor's physical isolation from the outside world in his room speaks to his general alienation from modern society, which expects him to work hard and find a wife. Despite the fact that he's finally gotten his wish, Gregor is overwhelmed with feelings of guilt and shame at being—literally—a parasite to his family. In the bleak world of the novella, happiness is impossible because the needs of the individual and society are irreconcilable yet equally compelling.
