Why is your god limited to the blood magic superstitions of the tribal desert dwellers of the time? For that matter, since there’s entirely no human corroboration it happened at all, why involve human methods at all? Why would a celestial, timeless, formless god need to process its anger in the mortal realm? Why not spawn a “soul” in heaven imbued with human knowledge, torture, kill it, and then have it re-spawn in heaven again? The results would be identical. Or, you know, not kill anything at all, and just get over yourself.
