When we look at the people of the past we often react in horror at their actions and question how any people of any age could be so barbaric or cruel. In comparison we imagine ourselves to be so much more refined, progressive, and civilized. We imagine we are simply better than them. The truth is that for all our pretensions, technological improvements, and delusions of grandeur, modern humans are barely any different than our ancestors. We are just as violent, barbaric, and brutal. We are just as cruel. We are just as bloodthirsty. And in no way is this more obvious than the mass, universal prevalence and acceptance of human sacrifice.
