Until the middle part of this volume, Dmitri, the eldest of three brothers, has been a mere side character.
But in this volume, he has a leading role as his suicidal journey to pursue Grushenka and the suspected murder of his father is highlighted.
To me Dmitri is a fascinating character in a different sense from others in this book.
As some critics point out, we can find similar personages in other Dostoevsky's works except Dmitri.
For example, Ivan is somewhat like Raskolnikov in Crime and Punishment, and the same is true for Alyosha and Myshkin in The Idiot.
However, Dmitri is so unique in his savage, honest, and impulsive nature that it's hard to find one like him.
His character makes the story vigorous and we can feel the same kind of tension and despair as he.
