That's true. It affected him a lot, even if he wasn't hurt too much physically, he was was still hurt with ptsd and mostly deaf for his entire life because of all the gunfire (earing aids worked but not very well). He always felt shameful about being a ww2 vet and the things he had to do and see. I always wished one day he would see it differently and see his actions helped deliver occupied cities and cleared out some concentration camps along with helping the war clean up efforts for 2 years after the war gave freedom to those who had lost it. We saw what it left behind, Dead or alive, there was a cost for all of them. He didn't talk about it much but he did say a few things when I had a school assignment. He joined when he was 16 and lied about his age, went towards the end and fought the Hitler youth, it felt like killing his little brother to him because they were his age but he had no choice because if he didn't they would have killed him. They ran into concentration camps by accident after the war while walking around. Saw the faces of live corpses lined up along the fence starved and nothing more than a sack of bones after it had been abandoned by the Nazis.
