MMA Mindset

Are we becoming more violent s a society?  The MMA, Mixed Martial Arts, is betting that we are.  Dove Medical Press can detail the damage inflicted in this sport.  The fact that we call it a sport tells us something.  The MMA is violent and largely just two men killing each other.  If you watch this sport then I have to wonder what violent need this fills.  Are we just animals after all or will we ever get beyond killing each other?  I am not a passive person but this sport just leaves me disappointed.  Isn’t boxing or football violent enough?
