Nest parasitism is not unique to cuckoos and you can’t really put a value judgement on evolution. Brown-headed cowbirds are the most common nest parasites in North America. There’s lots of species where the parents kill their own children if they either think they aren’t strong enough to survive or if the food supply is too insecure to care for them. It’s just nature.
