>>220959827Beheading near-universally plays an important part in cultures throughout the globe. The Celts of Western Europe held the decapitated head as a core aspect of their religion. The Japanese developed an etiquette around beheading that made it dishonourable to totally sever the head from the torso, and the ideal form was a slash that left a tiny part of the skin intact for the head to hang off of. The French had the Reign of Terror, and that one speaks for itself. Because a good portion of the human brain is dedicated to recognising heads and faces, decapitation carries a lot of staying power, because the head itself is a powerful symbol.
The beheading videos are simply a form of terror spread around by drug cartels to solidify their power base and intimidate rival cartels and civilians.
