If some of those children have been abused since a few months old and have never known a normal life, who will be capable of caring for them?  The degree of abuse the evil ones have committed against the children can not be undone by going to McDonald's and a therapist.  Could a person leave a child who has endured such evil alone with their own children?  Who knows what life they lived consisted of, could be that fear, horror and all sorts of evil are the only emotions they know or have experienced.
