The death of Ilyusha is one of the episodes being neglected, despite of its importance in The Brothers Karamazov. The death of Ilyusha, which becomes a structural link to the whole work, has comparable importance to the famous pieces, 〈The Grand Inquisitor〉 and 〈The Russian Monk〉, which convey the main themes of The Brothers Karamazov. Furthermore, considering the fact that there appears various deaths, such as the death of the Elder Zosima, the murder of Fyodor Karamazov, and the suicide of Smerdyakov, the death of Ilyusha reveals its philosophical as well as structural significance in the theme of death, connecting the topic of death and resurrection. In this sense, it becomes overlooking the mature artistry of Dostoevsky to regard the death as a simple one time episode or an auxiliary element for the theme of children or the role of Alyosha. As the vast majority of scholars agree, The Brothers Karamazov is a religious works. The fact that a verse of the Gospel of John is used as the epigraph of the work and the Elder Zosima is a monk who likes the contents of the Book of Job is to express the strong religious aspect of The Brothers Karamazov. It is true that the main character of the work likes the contents of the Book of Job and the Gospel of John, however, if they exist separately each other, the message of the work has weakened significantly. In this sense, it is necessary to pay attention to the secular element making The Brothers Karamazov as a religious work as well as connecting the two religious episodes. Self-sacrifice and salvation, which is the core content of the Gospel of John, and Theodicy of the Book of Job are embodied in the story of Ilyusha. The meaning of the epigraph, which is a verse of the Gospel of John, is realized by the death of Ilyusha, who left many sons to his father. The harmony between the boys and Alyosha after the death of innocent Ilyusha refutes the pretext of Ivan’s rebellion. Ilyusha becomes the ultimate integration of the contents of the verse of the Gospel of John and the Book of Job.
