Why is Hitler so bitter concerning the weimar republic?

Hitler was bitter towards the Weimar Republic because he perceived it as a symbol of Germany's defeat in World War I and the subsequent humiliation imposed by the Treaty of Versailles. He believed the republic was weak, corrupt, and failed to address the economic hardships and societal unrest that plagued Germany during the 1920s and early 1930s. This disillusionment fueled his desire to dismantle the democratic system and establish a totalitarian regime that would restore national pride and power. Moreover, Hitler blamed the republic's leaders for the perceived moral decay and chaos in German society.
