A large portion of failure of the eastern front must rest on hitler's shoulders as he failed to aim for one objective (i.e Moscow, Leningrad and Stalingrad) He disregarded one of the vital components of strategy ' have one goal and don't let anything distract you or lose sight of that goal. Hitler through his forces at all three, and failed to capture anything. In this regard he is a complete fool although he did achieve great bluffs at times like the bloodless war of Czechoslovakia.
