It was not until the 70s that the word Holocaust became a thing, this was also the time that so many muh, survivors, came out with these horrific stories. When you actually research the Nuremberg trials you will find that the defendants were beaten and threatened. Of course they were put to death, they had to be, so that they could never backtrack and plead their true innocence. Of course there were soldiers that were horrible people that did horrible things, this is always true of every war from both sides. Just keep in mind, history is always told by the winners and a lot of truths are lost.
