Rule 1 is Cardio. Rule 2 is Double Tap. I don't think any of these rule apply here though. Zombieland was an awesome movie though.

The fml clearly says it seemed badly injured. And how often do you see deer just laying down in the middle/on the side of the road without being dead or severely hurt?

deer DO NOT just lay on side of road, they don't get tired and take a break.

So if you're dog was in severe pain, with absolutely no hope of survival, you wouldn't put it to sleep? I agree the guy may have done it for the wrong reasons, but when a deer is lying in the middle of the road, can't even stand up, it has no hope. I mean, it should have run at the first sign of a car, and it didn't move. Even if the only injury it had was a broken leg, like horses, this would be a death sentence. Some horses to survive, after putting tens of thousands into vet bills and pure luck. Look at famous racehorses who get broken legs, if the vets can't save an animal that's worth millions, no vet is going to put a deer through that stress with a 99% chance of it just slowly dying. No one is going to give $25,000 to the vet to try to save a deer. The definition of humane is to not hurt an animal needlessly. What he did killed it instantly, it may not have been pretty, but what does that matter. I don't think the deer cared that it's death wasn't clinical, a quick death is a quick death regardless of how it's done. The person who really treated the deer inhumanely was the person who hit it in the first place and then left it to suffer (I suspect this is what happened, because I don't just think a predator would abandon it's kill in the middle of the road). Shooting it would have just scared the animal before it died, deer are scared of people, even in that state. To have to sit outside and aim a shot, getting reasonably close to it to ensure a quick death to the animal, and not a miss, would have been inhumane. To kill it with a knife, needing to get even closer to the animal would be inhumane. To call the police so the animal could wait longer while suffering only to get shot, would be inhumane. To bring it to a vet, which would surely terrify the animal, only for it to be put down, would be inhumane (and dangerous to all humans involved). I feel to be inhumane would be to prolong the animal's suffering any longer, and to cause it even more fear and stress before it died.

Deer just don't behave like that, they will run from pretty much everything besides that they only really lie down to sleep and they prefer sheltered quite places. If a deer is lying in the road and doesn't move when a car approaches it almost certainly can't move which means it won't survive.

Don't insult the hill billies. A hill billy would have at least made sure it didn't die in vain and made a meal out of it.

Not ashamed to say I have eaten deer that I found on the road. We live near a forest and have a lot of deer/car collisions. If I see it happen, I call the state troopers who tag the deer for me and I take it home with me.
