not all cultures are respectable. The Amorites or the Incas, for example. Cultures that treat humans like that are not respectable. The Amorites would rape their kids as homage to Baal. The Incas would sacrifice children to terrorize their subject peoples. As did the Mayans and Aztecs. The largest cache of sacrificial victims found was ~250,000 skulls, but there are tens of thousands of smaller sites with dozens to thousands.
