Modern humanism affirms the worth, dignity and autonomy of an individual and the right of every human being to the greatest possible freedom compatible with the rights of others. Humanists have a duty of care to all of humanity including future generations. Humanists believe that morality is an intrinsic part of human nature based on understanding and a concern for others, needing no external sanction.
Based on the principles of modern humanism…Hitler had no regards or natural affection for humanity or human life.  Specifically the Jews in the ways he invoked cruelty, barbarism, injustice and torturous treatment.  Which makes it hard to believe that he applied any type of humanism in his life.

Nazi camps were created under his regime showing that he wanted to impose his views of the world on everyone.  He persecuted and murdered over 6 millions Jews in all.  He (Hitler) treated them unjustly, had them put in concentration camps and tortured on a daily basis.  So why would Hitler have any obligation to care for anyone but himself and his army of followers?
