the ebb and flow of civilization thru out history has caused various human traits to be gained and lost over long periods of time . There is a trend of building civilization from scattered nomads to grand cities where most people lose their barbaric instincts and conform to society...

.. but some don't, some hold on to these older savage impulses and say they are living in the wrong time. These relics of a bygone time are out of place and yearn for the old days where the most brutal ruled and only the strong survived. These people may seem crazy for dreaming about nuclear holocaust or asteroid impacts or exotic dieses... but when extreme challenges face humans... these are the survivors who inevitably save the race and continue existence..
