One general comment about Hitler being "responsible for everything that went wrong" in Germany, I think there's a lot of post-war myth making and propaganda about that.
Hitler was quite like Stalin in that he developed a cult of personality and was a mass murdering ruthless dictator.
Hitler was quite unlike Stalin in that he was loyal to his subordinates and didn't play paranoia based power games with them where the losers got sent to the Gulag or to Lubyanka's basement and a bullet in the back of their heads. Hitler trusted his subordinates and had faith in them that they were loyal to him. Well, at least his NSDAP subordinates. He never trusted the Heer and rightly so.
Hitler was a micromanager and was indecisive. He would demand involvement in all decisions and do so right down to an absurdly low level for such a chief executive. He would conceive of some grand plan, demand it be implemented and then get a case of the nerves and countermand his orders. And then he'd countermand his countermanding. Hitler's subordinates could, at times, talk him out of otherwise bad decisions or talk him out his his constant countermanding. Plenty of his subordinates realized that a man who insisted on being involved in everything was a man who really couldn't be involved in anything. So, they took it upon themselves to implement "the Fuhrer's will" as they saw it. They operated on that "better to ask forgiveness than permission" doctrine. And they repeatedly got away with it.
Actions which would've wound up getting them shot - or worse - under Stalin got them just yelled at and held out of favor, for a while, under Hitler. And that was largely only if things didn't work out. If they proved useful instead, they were congratulated and left to carry on.
Two good examples of this are the StG 44 and the Me 262. Hitler was absolutely opposed to the production of the Sturmgewehr 44 figuring it to be a waste of production capacity and ammo. He forbid its production. Hitler was also so greatly impressed with the potential of the Me 262 that he ordered it into production over the opposition of the Luftwaffe and demanded that it be produced as a fighter bomber only.
In both these cases Hitler's subordinates made their own interpretation of "the Fuhrer's will" and directly violated his stated orders. The StG 44 went into production and the Messerschmitt company got their Me-262 lines running by churning out only pure interceptor versions of the Me 262 with no "jabos" - fighter bombers - being produced at all.
In each case, Hitler "flew into a rage" when he learned how his subordinates had violated his orders. And then those same subordinates talked enough reason into Hitler that he "came 'round" and accepted the reality.
Even outright failure would not get a subordinate put to death when it came to Hitler. Just look at Goering and what happened to him after his vaunted Luftwaffe first failed to break the RAF and then failed to beat the Soviets and then failed to defend the skies of the Reich. Yes, it cost him his status and position in Hitler's inner circle but Goering long outlived the Fuhrer despite falling from his graces. I don't think there's anyone in Stalin's top staff who could have boasted the same sort of treatment.
