'Human Nature' is different depending on the society that a person happens to have been raised in together with the intensity and type of indoctrination that person happens to have been conditioned for.
Finns, Swedes, Norwegians and Danes, for example, when faced with questions of how to respond to crime, drug abuse, economic well-being for the person and the nation, interpersonal relations, international relations, healthcare, personal ambition, meaning of life, etc, etc, etc... come up with different reactions and solutions to people from England, France, Germany, Japan, Canada, Cuba, India, Africa, Venezuela, Australia, The US Personal Libertarians, US Social Libertarians, US 'Jesusland'ers, etc, etc, etc...
I've lived with, talked to, drank with, argued with and debated ex pats from around the world, from Arkansas to Tokyo, Harare to Caracas. By instinct they are very different people.
There is no one 'human nature'. The instinct of one person is likely to be very different from the instinct of the next and extremely different to someone of a different tribe, nation, race, social class or religion.
We all need to breathe the same air, aside from that every aspect of 'humanity' is controlled by our genetics, our experiences, our education and our conditioning. There are large overlaps in many areas of human experience between peoples but we are all different, thankfully... Otherwise everyone would have the same set of instincts and there would never be an evolution of ideas.
Oh, and this should be interesting to anyone interested in Fascism.
