I agree, life can sometimes be so cruel, in some ways it can be more upsetting when it's a child's life that's taken away, because it not only affects that child's parents and family. It's also the future family chain that may have expanded and flourished in following years because of that one child, and of course their own families that may come along.
That' why I think it's even more tragic when it's children, I was married for over 48yrs, but we did have all those years together, and we raised 3 children, who now have children of their own, so if neither my wife or myself had not survived our childhood then a lot of future lives would have been affected or in reality never existed.
