What caused the fall of Hitler?

Answer 1

Hitler knew he would die from the people who were coming to get him so he shot himself

Let us see the situation he had got himself into, his evil wickedness caught up with him, being killed by his enemy's was too much for him to deal with, killing himself was the only logical answer to his way out of this world and by doing so he would not have to face the angry people for what he had done to their kinsmen , he was a coward and if you will notice he took the easiest way out of this life by killing himself...
