There are so many wonderful parents who have tragically lost children through no fault of their own, sometimes before they have even been born. Then of course there are many couples who would make wonderful parents; but through no fault of their own cannot conceive.
Then you hear about tragic stories like this one; where two utter scumbags have killed a lovely little 6 year old boy, who would have been treasured by so many other people, it does make you wonder why life can be so unfair.
