the horror the horror, what does that mean?

Rating: 8/10 (6 April 2018)

The war will turn you into a barbarian. When you lose judgment, you lose justice, then you lose humanity. then even you want to kill yourself. It is impossible for you to participate in a meaningless war. You kill people and go back to normal life after returning home. People are not machines. The true horror is who thinks this movie is telling you that go to war without judging it. As I read it in comments. the horror.. the horror......
