Who was the Greek hero who killed his children?

Answer

The quintessential hero, Herakles, embodies a paradox of heroism and asocial behavior: he tragically kills his own wife and children, and throughout his arduous tasks, he commits numerous acts of violence devoid of any moral integrity. When Kleomedes is referred to as a hero, it is neither ironic nor a deviation from expectations. His act of child murder is a standard entry in the heroic resume.
