We Need to Talk About Kevin

Rationalisation for Kevin's behavior is one of the central themes of the story: when asked the simple question "Why?" after the massacre, he responds that he is giving the public the excitement and scandal that they secretly crave. Only in rare instances does another side of Kevin emerge: in childhood when he becomes very ill, and later, just before he is transferred to an adult prison and is evidently nervous. Near the end of the book when asked for the first time by his mother "Why?," he responds, "I used to think I knew. Now I'm not so sure."
