Hitler wasn't seriously punished
The Putsch had failed and the Nazi Party and their newspaper were banned until 1925 which isolated them from politics.
The 16 dead Nazis were seen as heroes
Whilst in prison Hitler had time to realise that if he wanted control of Germany he'd have to do it through democratic means.
Hitler was shown to be a criminal, hot-headed, and guilty of treason.
Hitler was seen as a failure and many believed the putsch would be the end of the Nazis.
