A Jewish doctor treated Hitler’s Mother(The only person Adolf ever truly loved) while she was dying of cancer.
He promised his eternal gratitude to the doctor and even after becoming a pathological anti-Semite and later the Fuhrer, he was true to his word and was adamant the doctor and his family be placed under protection from the purge.
While some may think this an act of genuine kindness, I just think about all the lives lost because Hitler never stopped to think that all Jews were capable of good and not just the one who happened to have been good to him because of immediate proximity..
