It does belong to the parents because they have a right to see their child born, instead of chopped to pieces. To mourn the death and burial of their child, as a whole baby.
You wouldn't understand unless you yourself have conceived and then lost a child I suppose. Most mothers, it would be unfathomable to do what is done to them in the process of abortion.
That 30 second life, that 4 minute life, that is owed to that child. That one breath, those few heart beats. That doesn't belong to you.
