The most prominent characteristic of mankind

     In ur opinion

     The most prominent characteristic of mankind that has been the main cause of the struggles is?

Please explain why!

I really liked your perspective on it.

As a matter of fact different combinations of the feelings and the one`s mental calculations(under the rules of doctrines or beliefs) to get more benefit for him/herself now or hereafter(except alturism) result in a different identity.I aggree with you,BUT I think if all the resources were infinite,there would still be struggles among us. So the potential feelings are sometimes triggered unreasonably .It is impossible to control all the interior and exterior factors for each individual or each group of people(because sometimes it is easy for mankind to be provoked to behave as a whole) to reveal the reality by experimentation ethologially for human being. However it is possible for one to discover physical and spirutual features behind his/her attitudes by some disciplinary limitations voluntarily.I meant that most of the people around the world do not know how they could discover their weakness and power,and how to control those. That it is our nature to fight with eachother and some moral or secular standards of behaviour have been proposed up to the present.

   Now I am asking another question

   What makes a person to be disciplined or controlled in a better manner?Can you tell me the best way of controlling individuals or groups for a best society?
