Kirillovich is the prosecutor who makes the case against Dmitri. He's not stupid; he just overestimates his talents. The narrator mocks his "artistic pretensions – for example, to psychologism, to a special knowledge of the human soul, to a special gift of comprehending the criminal and his crime" (9.2.1).
