how was the relationship of karamazov brothers?

Fyodor’s oldest son (whose mother is Adelaida). He is impulsive and quick to anger like his father, but he has a faith in God that Fyodor does not share. He is convicted of killing Fyodor.

Fyodor’s second son (his first by Sofia). He is intellectual and cynical, and he becomes very ill when his father is murdered because he feels that he is very much to blame.

Fyodor’s youngest son (his second by Sofia). He is deeply religious and caring, and he tries to follow in the footsteps of Father Zossima, the elder at the monastery whom he respects very much.

These brothers are so different they often clash in different ways.
