The author expresses how younger generations looked up to their parents, teachers, governors, etc. Despite that, as the young ones grow up they realize the old generation way caused a lot of pain, death and war between socities. Thus, now the young generations want to quit the ways of their parents but because of this they are called cowards or revolutionary. In the end, the author points out that it is not about cowardy or betrayal, the younger generations feel alone because they can't follow the olders' path, it's up to them to walk in a different direction or to keep getting the same results of pain and death as before.
The main point is the disappointment of the younger generations after realizing that the teachings of the older generations were wrong. The values they held dear were false. Stark reality depicted a totally different world from the one their elders had glorified. In the aftermath,there was nothing left but loneliness.
