You find things like this interesting? You make it sound natural. What an awful perspective on this situation.
It is natural, and it is interesting for anyone who is interested in social behavior or anyone who finds it interesting to link how humans act compared to how other species of the animal world act. Every psychologist in the world right now is finding this interesting, not that I am one, but it's the same basic interest.
Everyone already knows it's sad, I don't have to say it is, it already is. However, it's also very interesting to me on a social/naturalistic level. There's nothing wrong with that.
