There was everything in the war. And German soldiers rescued Soviet children, and Soviet soldiers murdered, robbed and raped civilians in Europe. Simply "uncomfortable" facts are well filtered. There was no internet, it was much easier to control the people.
Everything happened in the war, you are right. And cases of barbarism, rape among Soviet soldiers of course happened. The only punishment for this was a shot. And this is not propaganda, this was told to me by a participant in the event.
The Germans are harder. There were also cases of rescuing children, and entire families, and even Jews (now about this Oscar-winning films are filming, a blessed theme). It was only more common when the Germans burned each village together with the inhabitants, but if they suspected ties with the partisans, they must be burned.
Well, about the memories of the inhabitants of the occupation I do not need to read - two aunts lived under the Germans for six months, I still remember how their faces darkened when the conversation about it entered. They didn’t like to tell the truth about it, they were limited to "terrible it was", "abuse", once only I, a 10-year-old boy, listened to how they and some other aunt remembered it. Really scary.
