(WARNING: Potentially insensitive analogy ahead)
While here in South Carolina, I saw both a dead cat and a dead dog on the side of the road (not at the same time). It's a sad sight to begin with, and then I think about how that that cat and that dog were probably someone's pets, and some unfortunate family is just devastated because their four-legged family member got hit by a car, and that makes it even sadder.
Now imagine that it's someone's mom or dad or grandma or brother or son, and they got shot or blown up for no good reason other than that they were in the wrong place at the wrong time.
Now imagine that there's hundreds of thousands of them.
