If one person dies I feel it far more than if a group dies. The larger the group, the less emotion I feel over it.
When I hear about a child being murdered, it is very painful. I hear about the tsunami in asia, and it's more a curiosity. I feel bad, but not nearly as bad as if I hear about one death. It's like I can relate one person at a time, but when you get more than that I can't.
