Carthie child sacrifice is a problematic issue. Diodoros Sikulos says they did - hundreds of children of aristocratic families in fact, being placed in a statue that then precipitated them into a fire. Archaeology hasn't confirmed the truth of the statement, but certainly the burned remains of many many children were found in the Tophet at Carthage. The only question on that account that remains is whether the children were dead or undead when they or their remains were burned. One option may make you feel better about them but the other one sure sounds like archaeology confirming a written account.
