text: why do people kill each other?   short answer.., fear longer answer, it's in our genetic make-up. as organisms, we are programed to survive and reproduce. as complex organisms with social structures, we have acquired competitive responses which enable us to acquire and control resources and power. again, to better satisfy the original directive of survival and reproduction.  fear... of danger, survival, safety of our offspring, losing of resources or power ..... all will engage the competitive response to kill.......... we are organisms that kill  out of fear  ( culture either curbs or augments this primal response )
