In the book "Runner with the Wind" the protagonist betrays his best friend as a child, for which he pays for his whole life. And then, through a series of miraculous coincidences, he finds the son of this friend and adopts him. Firstly, while reading it, it seemed to me all the time that the author was making an angel in the flesh out of this devoted friend: he is all such an ideal, the only bright character (so far absolutely all other heroes, even the main "villain", have both positive and negative features). And the betrayal did not anger him in any way, and molestation in childhood almost did not affect his character. All this is revealed in the last pages and looks too one-sided. It would be much more interesting for me to read how a friend passed the same evolutionary path as the main character who betrayed him.
I really do not like works in which the point is the suicide of the main characters. Now you will probably think that I am a sadistic reader) But in fact, how people will cope with mental trauma throughout their lives is much more interesting and voluminous than just “... she threw herself off a cliff. The end". Such works include Ostrovsky's The Thunderstorm, Tolstoy's Anna Karenina.
It is interesting to know your opinion. Perhaps we have common views on this.
