I wouldn't even go that far. We are a fear based society. Anything that could cause harm is bad. This is as far removed from being natural as one can get, imho.
I assume we are speaking about the US. Only immediate physical harm is considered bad. On the other hand long term harmful conditions like the oversupply of junk food, overworking, lack of vacation or the health care situation are considered normal.
Unless the thing is guns, then it doesn't matter how many children are killed.
