Child Murder in Iraq

I was looking at a piece in the Toronto Star on children being deliberately murdered as they were left inside a car bomb in Bagdad

Police said today that children were used in a weekend car bombing in which the driver gained permission to park in a busy shopping area after he pointed out that he was leaving his children in the back seat.

The driver then ran away and detonated a bomb, killing the children and eight bystanders.

What other than outright murderous criminality can justify such an act? Does anyone support such an act? If anyone does support such acts haven't they resigned from membership of humanity?
