It is despicable to kill children.
It is not despicable to point out that they are dead.

Perhaps the fact that they can't defend themselves? Or that you can't say that you just made the world better eliminating some dangerous terrorists? Or the fact that they had their whole life to live? You only have to choose.
That's pretty chilling.
