Suicide letter

The ideal character, according to the author, should be crazy. However, all crazy suicides in the letter remain, in fact, outside the text, due to plot reasons, falling out of the narrative. Therefore, the author could only add a fraction of abnormality to the main characters, while retaining the relative realism of what is happening. And this is the only reason for the appearance of psychotropic substances in the novel. The author is not a follower of psychedelic philosophy and does not propagate drugs.
It should also be emphasized that the author is only interested in the abstract side of the work - the author does not express his political, moral or worldview positions in the novel and does not consider the topic of Stalinism, as it may seem at first glance.
The only motive that can be seen in this text is the motive for misunderstanding between people. Everything else should be attributed to the speculations of the reader himself
