Hitler restored the pride of the German people. That’s what overcame that moral fortitude. Pride and greed are very, very powerful motivators.
Pretty much lots of people also hated the jews and saw anything right from germany the people as animals ( also something most of those documentairy's won't talk about because not the fibe they want to create ), then with propaganda being spread and people being extremely young in general it was easy to get stuff to go the way it did.
Like those soldiers in that documentairy said, i grew up with that guy i fought with and then he got rained with bullits from top to bottom, that guy will no longer have any "moral problems" against his enemy. And start to push boundaries further and further which creates more and more disgusting environment which people then start to follow just to not be on the other side of the line. Because turning on people in that area was incredible easy. U don't align with us? traitor, hidden jew etc.
The whole moral discussion about "well morally u shouldn't do it" is all stuff people try to reflect on now and how things where or not. If you where not visiting the book burning crusades in your town in a full hitler outfit u would be seen as a hidden jew or a traitor and shot the next day. It's easy talk now when u sit behind a PC and nothing happens to you.
Also good luck making a stance, when your commander throws baby's into a ditch, hammers pregnant woman to death and shoot and hangs kids as national sport. WIth a wasp of traumatized soldiers that only want to fight and would cull u the next day if needed. U even see the turning on eachother in politics all day long now imagine if you had to gamble with your life and get no stage in a backyard, yea good luck with that.
There was a reason why that kid runned as german soldier over towards swiss i believe. If he complained he would be in the ditch next towards them.
It's like standing in a black life matters group of people, and say n word endlessly and that they all need to die. But they all are loaded with guns and are busy already executing woman and children like its national sport day the entire day, u will join them into that mass grave 10 seconds later. Specially when there is nothing to judge or stop them even remotely. Easy talk. There is a reason why solders fled and deserted instead of confront.
Even those commanders that got recorded didn't dare to speak even under there own commanders while in jail anything critical because they where afraid of the backslash it would create for them and there family's which would be next in line to be culled. Also something people don't realize. A tactic even left starts to use in the US now, if they can't harass the target person they will go towards there kids.
And this is what is mostly wrong with the modern day of looking at how things are, we look it through the eyes of current generations views where killing a bunny in the woods is already seen as unhuman ( yea this is not a joke, most people don't make the elite squats in militairy because they can't kill a animal for food ).
While when u are in a war invested enviroment with nothing to eat, u will eat freaking worms and grass and kill whatever has 4 legs to roast it even if its a rat a cat or a neighbor dog. Lots of them where sick and tired of everything that happened in that area with deep depressions, zero pride and zero way forwards. U will bite on whatever comes your way.
Most of the documentairy's do not align up much with what people really think. You think they would interview a german and say the jews deserved it? ofcourse not because he's on the culling list the next day and the documentary will be called white nazi supremacist material and the writer will be culled.
Even today we got people deadly afraid to say there opinion. Go stand in china next toward the president and his death squad that shoot woman and children and harvest organs all day long that u think those people are disgusting and china needs freedom. Yea do you honestly think u will walk outside still alive? lol nope.
