Here I will take the heartless position and say that it is not clear to me that this statement is true. I certainly agree that it's a tragedy for the people involved. But if 4.4% of children dying before age 15 means that the world is an awful place, at what point would that stop being true? 2.2%? 1E-10%? I don't think the world is an awful place, I think it's a good place, getting better in some ways, with a long way to go in many others.
