Human's Stereotype

Like it or not, the bottom line is human's stereotype is simple, selfish, egotistic or even aggressive (It should not rule out that many of us are nice, friendly, reasonable and peaceful). Without quality education, without disciplinary and punitive actions and without rewarding living environment conducive to harmony& integration of understanding and social justice, people are prone to exploiting their superiority, ego and innate might to manipulate and violate the other people.  The above in-dept truth explicitly explains to why “check&balance” measurement and “rule of law” must have meaningful and genuine place in one society!  (No offense! A case of study only!)
