I don’t know why you are being downvoted. Whether it is ritualistic human sacrifice or pushing native Americans onto reservations, it is all versions of trading human lives for our own benefit. This takes many forms from the person who uses another person’s body for their own sexual gratification to wage theft to murdering people in a ritualistic setting to curry a God’s favor. It is all about how can I use others (other’s time, bodies, possessions, lives, etc.) to get gain for myself.
