Well being a student of Sociology i do feel every society has it's norms and values so the behavioral traits are originated from those norms, mores and value system of a specific society.
I am also convinced that we all are the same with one origin as whole, with egoistic approach towards life.
A very well versed and researched article, thanks for your contribution @kyriacos
I am really looking forward to hear more from you :)
Stay Blessed, Steem On!
