They're all retards throwing around the hot potato. Jesus was the only one calling out the retardation.
Burnt offerings are a regular thing in the Old Testament. Still figuring that one out but it is basically a 'scent offering'. You know that heavenly smell of barbequed meat? Jesus changed the game via his Bloodsake though and isn't required anymore, among other things.
Otherwise if you're just killing animals to drink it's blood like the Satanists do, that's an adrenochrome addiction which makes people bloodcrazy.
