This is my other paragraph of my essay. can someone please reread it and help me

In A Farewell to Arms, the primary theme is war. Some of the characters remain neutral about the war, and some remain bitter about the troubles it brings in life. Lieutenant Frederic Henry, an Italian ambulance driver, enters the war looking for adventure, but ends up finding no honor. He finds himself tired of the fighting and conflict and realizes he has to escape the war. Towards the end of the novel, the Italian forces become weak and lose many battles resulting the sinking of morale and confidence the troops need. Rinaldi, one of Henry’s friends, even finds himself exhausted from overworking. “This war is killing me.” This man, who once was completely happy in his life has now lost his willpower to live proving that war brings pain to everyone. In one incident, Henry is forced to shoot an engineer for not helping free the truck from the mud, which surprises the readers because he usually follows rules of being an officer. Henry believes that killing is unethical, but he justifies it by saying that the war caused him to shoot. Just like the engineer’s death, Hemingway explains that war between nations is unstoppable.
