The Carthaginian civilisation sacrificed their first born children. The Aztec civiisation waged war to get prisoners to sacrifice to the sun god. The Roman civilisation crucified all the slaves belonging to a master who had been murdered by one of them. The Jewish civilisation executed women for adultery. The European civilisation of the 16th and 17th centuries had thousands of people burned as witches. Civilisation is an incremental thing, and what was best practice then is unacceptable now. Ragusa in the 16th century had the death penalty, but it was inflicted extremely infrequently. The executioner was recruited from elsewhere, the city shut down for the day and citizens remained at home, and after the sentence was carried out, the executioner was paid handsomely, sent home, and ordered never to return. That was a shinig exemplar for then.
