A lot cultures practiced some form of human sacrifice, even the Romans when things got really bad. There could have been huge mass killings for all I know. But I read some where, I forgot the name of the book, where the Romans claimed the druids worshipped in groves that had oegans hanging off trees. There could not have been a large scale sacrifice all that often or things would have started to collapse look at Rapa Nui as an example.
