There's a difference between being captured by the Allies and captured by the Soviets.
Scenario 1: Hitler's inner circle finally turns on him and sedates him through a drug administered by his personal doctor. They get the hell out of Berlin and go West in hopes of surrendering to the Americans, believing that they will be treated well. Hitler is put on trial at Neuremberg and is found guilty of crimes against humanity. He is summarily executed. If he is deemed mentally unfit to stand trial, he is imprisoned for life in a mental health facility (perhaps in the United States) for treatment.
Scenario 2: Soviet troops breach the German defenses early and reach the heart of Berlin. They discover the bunker and invade it, taking it by storm. Hitler is either captured while trying to escape, or discovered hiding in one of the rooms in the bunker. If the Soviets don't shoot him on sight, he is captured, beaten, and dragged off to the East, where he either faces imprisonment in a gulag or execution after a farce trial.
