Even at the dawn of large heirarchical societies, human sacrifice existed.
Ritual murder was not particularly subtle in execution 4 to 8 thousand years ago. Today world is by comparison a marvel in sophistication in the arts and sciences of death.
By advancing ever more emotionally addictive narratives based on the myth of redemptive violence, we sacrifice millions of lives here in just these United States of America.
This is done so well, with such slow, deliberate precision, that most of us, are unaware our lives are cut short by 20, 30, even 50 years.
Eve if we are peripherally aware of the horror, more often than not, the architects of this mass murder, engineer it literally with our blessing and with such efficacy that victims by turn compete for the privilege to die or as just as likely blame themselves and or each other for their demise.
