How did hitler trick the German people into doing evil

Hitler was born in Austria and when he was a little kid him and his family moved to Germany. When he got older he entered ww1 as a messager. During the war his best friend got killed right next to him and that impacted his life. When he got older he became the leader of the nationalist party of Germany or known as the Nazi party. When he was running for the leader of Germany he told the people that he would get them out of the great depression by starting having the factories build war materials like tanks and bullets. But Germany didn’t know what he was planning. In 1939 Hitler attacked Poland and ww2 started.
