It is a heartbreaking tragedy when illness/incurable disease takes the life of one's child. When the COD is DBP (Death By Parent) there is no true equitable justifiable punishment for the evil murderer. How does one calculate the "worth" and measure the deprivation/loss of the life experience span of discovery, wonder, accomplishments, along with pleasure and pain of the child gone too soon. The possible contributions eliminated along with what might have been, the unknown scientific discoveries - who can say what impact all the murdered children could have made on all of society. We will never know what these children may have accomplished if allowed to live out their normal life spans.
