Of course, Hitler "helped" people make the choice by putting up propaganda. The dictionary meaning is this: "Chiefly derogatory information, esp. of a biased or misleading nature, used to promote or publicize a particular political cause or point of view". Hitler put on his posters and in his speeches that Jews were rich, greedy, arrogant, and responsible for the economic crisis and the loss of the Great War, and that Germans are the perfect race. Naturally, most people sympathized with Hitler.
Jews tried to get out of the country and send out the children through the Kindertransport, and a few succeeded. But some children had to go on their own while their parents stayed behind. Many families never saw each other again. And all the while Hitler was taking his brainwashing to new extremes, hypnotizing the German people.
