You mean what literally every society and culture was doing for all of human history? Native tribes across the globe were in perpetual war. Why do you think it was called the Aztec Empire as just one example? Every primitive culture would have done the same thing if they had the technology. Deception is a recurring theme in The Art of War and similar strategic works across time. Ancient Greece, ancient Rome, China, Persia, Islamic empires, etc.
>You are pointing out rituals in the rest of the world but these were occassional ceremonies.
lol no they weren't, human sacrifice happened dozens of times a day every day in Mayan and Aztec civilization. Cannibalism was a regular staple in many native American and African tribes.
All your comments on cannibalism are complete bullshit. The mummy eating stuff was basically over by the 17th century, except in rare instances.
Eating mummies is also completely different from literally killing someone for the purpose of eating them, or decapitating/ripping the heart out of someone for human sacrifice.
For someone claiming objective facts you certainly don't have any.
