I don't want to douse your theorycrafting, but the brand of sacrifice is from a Japanese comic called Berserk.
It's from Berserk. The people who are marked with the brand are sacrificed during the Eclipse to give birth to a new God Hand.
In that case Griffith sacrificed his comrades, the Band of the Hawk, in order to become the fifth and final God Hand.
lmao whatever you say, neckbeard.
