Just watched “Hacksaw Ridge” the other night. The story revolves around Lt. Duff, a religious dude who comes of age during WWII. The thrust of the story is that he has a sort of religious awakening at a young age after a fight with his younger brother. Drunk dad just sits there and watches them duke it out in the yard. Mom is all like, “Why are they fighting?” Dad takes a swig and says, “When did they ever need a reason?” But it escalates when young Duff whacks his brother in the head with a brick. Did he just kill his brother? Suddenly Dad is pissed, pandemonium, everybody is yelling, he’s going to get a whupping, and worst of all, he may have killed his brother. Devastating guilt. He sort of hides in a corner of the house with an illustrated poster featuring the 10 Commandments. While everyone is freaking out, he stares at the picture of Cain smashing Abel in the head with a rock, exactly like he has just done, Thou Shalt Not Kill.
So, he’s this sort of innocent rural guy who has a foundational experience of nearly killing his brother that puts the fear of God into him such that he will never engage in violence again. He couldn’t live with himself if he ever did. When the war breaks out, everybody enlists, including him. He figures he’ll serve as a medic. The Army isn’t exactly cool with this- he won’t touch a rifle, period. He gets mocked, he gets beat up, he gets courts martialled and misses his own wedding. Shrinks interview him, try to get him to change his mind, ask him if he is hearing voices or if God is telling him what to do. “No, I pray and like to think God is listening, but it isn’t like a real conversation.” (<- the answer to the OP btw, he just acts on what he believes, but isn’t hearing voices, and it never goes into whether he thinks the Earth is 6000 years old or any of that) But he won’t give in. Finally they are like, fuck it, let him be a medic, the commander says this question has already been decided and we can’t kick him out.
So he ends up with the troop at the battle for Okinawa. The Japs are fierce, it is a freaking bloodbath (doubly so because it is directed by Mel Gibson), and he scurries around trying to rescue the fallen comrades. He even helps out a few wounded Japs. He is just the nicest guy, but no matter what, he will not try to kill anybody, only try to help. The troop gets driven off the ridge by a counter attack, but Duff remains behind all night long, dragging wounded soldiers from the field and lowering them down the cliff with ropes, dodging the Japs. He rescues 75 men, receives the Medal of Honor.
It did not seem like the guy was delusional. He saw his drunk dad be a broken man after having to violate everything he’d believed in WWI. He doesn’t want to make the same mistake and end up the same way, difficult as it is. War is hell and madness but he wants to demonstrate that we don’t Really have to kill each other while also preserving his sanity as he sees it. God and his experiences are mixed up in it all and in the end he comes out a hero. Based on a true story, a good show whether or not you are a religious person.
