News Flash: deer die from other causes than human. The bacteria that are going to have the last meal from it don't care whose gut it goes through first. There's more conservation going on in that picture than happens on a den wall or down a toilet.

It does look like its hindquarters may be missing a bit, maybe had its gut opened up. Two years ago I found a doe half covered with forest litter and only slightly nibbled. I figured it was black bear did it. I don't get this outrage thing, when a wild species winds up dead from another wild species.
I find the roadkill count a lot more disturbing. When you add the number that die right on the road to the number that crawl off to die out of sight, it's downright disgusting.
