Sara Ann Ashcraft on twitter explained it well. The adrenochrome. It rings true to me, even though I have never seen actual footage of it. If your hypothesis is based on lack of visual proof, then your hypothesis is flawed. That is top secret stuff to them, just like our govt/mil has top secret stuff you will never know about. You can choose to believe those who had lived thru it and tell their story, or disregard it.
If you think it's not real because there are pharma pills to take to serve the same purpose, you are ignoring the reason they do it to begin with. It's not just about the adrenochrome or just about the human sacrifice or just about the cannibalism. It's the totally of them combined. Think rape. It's about control. That's not about sex. It's about dominance and control.
Do you believe there are those that enjoy torturing people to death? What they do are rituals that are handed down generation after generation. No amount of artificial drugs will change/stop the rituals.
It is so sick, it's easy to want to dismiss such horrific acts. Society is not quite ready for it, but I believe soon they will be. It is just coming into the spotlight how immense the sex trafficking/pedophilia/satan worshipping that has been going on right in front of our eyes. After a time, society will be able to accept the truly demonic practices that is prevalent in our world today.
