Say to the people of Israel, Any one of the people of Israel or of the strangers who sojourn in Israel who gives any of his children to Molech shall surely be put to death. The people of the land shall stone him with stones.
Leviticus 20:2

Human sacrifice isn't just murder. It takes the very image of the Creator of Man and destroys it in honor of a fake god. It is a picture of the nature of all false religion.
