In front of the film, Desmond Doss's life experience and what happened when he was a child and young were introduced in great detail, so he swore to God that he would never kill anyone and never pick up a gun. This is indeed a wonderful scene in a war movie, but it is about faith and self. Without this belief, there is no self, and there is no point in living in this world. From this perspective, this film is more like a film with the theme of religious belief, which highlights the power of faith. In the climax of the film, it is this belief that gives Desmond the strength to save 75 comrades-in-arms like hell on the battlefield. We can say that he is crazy, that he is insane or even crazy. But we can't deny his greatness.
In the Battle of Jigsaw Ridge in Okinawa, Dawes stayed alone on the battlefield, braved the bullets and saved the injured comrades without hesitation, narrowly escaped death, and finally miraculously survived! Dawes is a superhero among heroes and a legend like God. Dawes never fired a shot, never killed anyone, and insisted on the belief of not killing people from beginning to end. He became the first "objector" in history, a soldier who won the highest medal of honor of the US military without killing an enemy.
Human nature is greedy, and war is an aggressive strategy to satisfy its greed. If Japan hadn't bombed the Pearl Island of the United States, the United States might have looked at the war with the idea of "the fisherman gains", but as Chief Executive Doss said in the film, in order to protect our cherished family, we must win the war.
