Is the war a social autoimmune disease?

Is the war an autoimmune disease in human social life? If only fear was involved in the mechanism of wars, we could compare both of the disorders, but fear is not the only  factor for wars. Greed is another factor that is also responsible for wars. First human killing took place on this earth was not from fear, but greed. whatever the reason conceives the human brain for this evil, but one thing is certain that it if we consider whole humanity as one unit, this phenomenon of war performs the same action in human social life as does the autoimmune disease in human body. History that is full of wars, limits our vision, never allows us to think on the broader visions to even think it possible to have a world without wars. With great development in science and technology,we humans have not been able to develop our social sciences that could either stop the wars or limit them.
