I'm a big WWII buff and one thing most people don't realize is the Germans were not overall savage to everyone. The POWs and the artists from the West were given "adequate" treatment by the Germans. In fact American Jews in POW camps were not subject to the treatment given the other Jews.
The camps were not universally horrible. You could be in one section of a camp and treated within reason, while other people were treated horribly across the camp.
The Western POWs were generally treated with in the bounds of the Geneva Convention, while the Russian and other POWS were treated as slaves and animals.
Obviously no one in a POW camp or a concentration camp was treated well, but the Germans were not universally horrible to all prisoners. The holocaust tends to override this and it was possible to be treated humanly in a camp even while others in the same camp were gassed, starved and worked to death.
Your treatment depended on your classification and what country you came from.
This is one of the reason the Germans surrendered quickly to the Ameicans and British, while fighting on to the bitter end against the Russians
