Unfortunately, the Great Depression led to the rise of the Nazi Party in Germany. Everyone should have done more to prevent the rise of Adolf Hitler once his rhetoric and "Mein Kempf" were published as Gospel truth. Europe could have stood up to the Nazis. Germans should have stood up to the Nazis. The Centre Party, based on Catholic beliefs, most definitely should have done more to prevent the rise of Hitler's awful path of destruction.
The Centre Party, like most others, likely didn't know Hitlers true goals or what would come of the Nazi party. However, any party that shows signs of possibly hating, posing a threat to, or hurting groups of people, should not be allowed into power and should be prevented from rising to power as much as is possible.
Hindsight is indeed 20/20, and when looking back on the terrible times of the Nazi Party, many people would like to think someone should have stopped them before it was too late. This however is irrelevant, because the facts are Hitler and his Nazi party were incredibly likable, and rose to power because the people wanted it.
Yes, the Centre Party should have done more to prevent the Nazi party from taking over. But I don't think any world government at the time anticipated how bad the Nazis were going to be for Germany and Europe. Even with the best intentions, the Centre Party couldn't have stopped the rise of the Nazis anyway.
No, this party of Germany should not have tried harder to prevent the rise of the Nazis, because at the time in Germany there was no slowing their rise down. Hitler was to powerful, and had most of Germany behind him in his quest for world power, so they needed to stay back.
