Was Hitler always angry

Most biographers, for example Ian Kershaw, have no doubt that Hitler's fits of rage when speaking in public were all part of the act. In other Words, they were put on deliberately in order to show that he was angry and he wouldn't tolerate any contradiction ... Abroad, Hitler's public outbursts of the shrieking ab-dabs contributed to the view of Nazi Germany as a madhouse. (There are brilliant take-offs in the movie The Great Dictator, starring Charlie Chaplin. The film was released in September 1940). Even in Nazi Germany some people made jokes about Hitler chewing the carpet though it could get one into serious trouble. As for fits of rage in private, who knows?
