Germany was in a bad state when Hitler took power. The effects of the depression took a great toll on the German people - Hitler blamed the Jews for such problems and promised the Germans to return their nation to its previous glory. Some bought into this - considering the problems were great - and saw as Hitler improved their lives. I'm not saying it was right, but considering the conditions, the Germans were willing to believe almost anything that would solve their problems. So, yes, some of them, agreed with Hitler and were anti-Semitic.
Others were scared. They were neighbors with the Jews, and quite friendly with them. They knew quite well that the Jews had nothing to do with Germany's economic crisis. But once Hitler gained power, he SLOWLY started taking away the Jews' liberties. It was small things at first - turn in your radios, your bicycles, follow curfew. Then it got worse - wear the Star of David on your coats at all times. And then the bloodshed begin. Kristallnacht took place in 1937 - and things deteriorated after that. While some Germans took the risk of hiding Jews, helping them escape, and doing other things to undermine the Nazis, some were scared for their own lives. (As selfish as it is, and as much as we may condemn them today, you have to understand their position. Seeing such things happen and wanting to save yourself and your family was human nature.) Therefore, there were some Germans that had to turn away from the Nazi's actions.
Indifference. There were a number of bystanders who watched as the Nazis hauled away Jews, homosexuals, Gypsies, Jehovah's witnesses, physically/mentally handicapped, etc. These people are very different from those described in #2 - while some truly felt remorse for their Jewish brothers and sisters, these bystanders were self-serving people who could care less about what happened to the Jews. They may or may not have shared Hitler's beliefs, but they certainly did little to stop it. There's a poem by Martin Niemoller called "First they came." (It's very short, but it gives you an idea of one of these perspectives. You definitely should look it up.)
Anyways most of the German people (citizens / civilians) did not directly do Hitler's dirty work [they were NOT Nazi soldiers working at camps]. But many believed in his doctrines or were forced to believe (in order to protect their families). You have to know that not all Germans were cruel and brutal Nazis. Some really wanted to help and either did resist or their efforts were hampered by obligations. (In that time, just because you believed the Nazis were doing bad work didn't mean that you just stood up to them - you had to think about your family, etc.) But then again, keep in mind, there were people who knew the Nazis were doing bad stuff and chose to turn their eyes and completely ignore the injustice. Therefore, Germany was not just one group of people - but a nation with many different perspectives. Hope that helps, good luck!
