Oh there is always another take on the story, and I am not sure that my own one is the 'right one' ... It's just the one that that I think of. He was still a Nazi and the company that 'intervened' for him was one of the main recipients for slave labour, and probably responsible for for more deaths than the people he saved in Nanjing.
I think that he even said himself it was more about him being close to the Chinese people that moved him to action.
Again, I'm not saying I am right, just that such an entity as 'the Nazis' can only get away with what they did because the vast majority of people chose to either go along, or actively participate.
Agreed, there is always another perspective. And, yes, it was respect for those who lived around him that goaded Rabe into action.
Personally, I look at the actions of individuals, not groups. I do not think the vast majority of Germans had any clue what was going on behind the barbed wire, and asking questions was detrimental not only to your health, but the health of your loved ones. The Gestapo serves a higher power, and they do not not play fair.
There was an interview with a boy who grew up idolizing Hitler, a member of the Hitler youth, who felt intimately the charisma Hitler exuded. He stated the Jews were needed for slave labor, to keep the factories running to release troops into the field; after the war, seeing the resources poured into the Camps at the expense of the army, it caused a sea change in his understanding of the Reich and has spent the rest of his life asking questions rather than repeating Hitler's answers.
Stories like Oskar Schindler and John Rabe reaffirm my faith in humanity. These are flawed human beings, card carrying Nazis, who chose humanity over the Party when put on the horns of a dilemna. Rabe, taking a personal risk, saved the lives of others; he was punished by his own nation for trying to retell the truth of the attrocity, then punished again by the Allies simply because he was a Nazi.
