Dostoevsky intended to write a sequel, which would detail the rest of Alyosha's life, but died shortly after the publication of The Brothers Karamazov.
He becomes acquainted with, and later engaged to, a young girl named Liza (or Lise) Khokhlakov, daughter to a confidante of Katerina Ivanovna's.
Alyosha is also involved in a side story in which he befriends a group of school boys whose fate adds a hopeful message to the conclusion of an otherwise tragic novel.
Predrag Cicovacki states that Alyosha, like Prince Myshkin, the protagonist in another Dostoyevsky novel, The Idiot, are almost Jesus-like characters, who are nevertheless unable to prevent the suffering of those around them.
Dostoevsky is believed to have based the character of Alyosha on his friend, Vladimir Solovyov, a Russian philosopher and poet who led a generous life, to the point of giving away his clothes to people in the street.
