Answer:
The narrator acknowledges that war is cruel, unjust, and inescapable.
Step-by-step explanation:
This is what Hemingway's indirect characterization of the narrator reveals. In this passage, the narrator and another character (Passini) are talking about what would happen if the war were to end. Passini claims that he wants the war to be over, and that he wants to go home. The narrator, however, is skeptical of this view. He believes that even if the war were over, what would be left would be much worse, and the fight would not be over. The narrator believes that war is cruel, unjust and inescapable, and has made up his mind to continue fighting until the end.
