Here's one bit I was thinking of:
The important idea is that everyone should follow the same rules. Thus, if a human ranger can go out and kill a deer with a Survival check, it would also be reasonable to expect that a Red Dragon could go out and kill a PC with a Survival check. Comparable scenarios.
Is that what you think should happen? I'm guessing if your PC died that way, you wouldn't be thrilled.
To me, the idea of killing a creature by hunting, would be (potentially) an example of where the DM might want to cheat. That is, when I go and say that the players found some food and include a living creature that was killed as part of it, I'm cheating a bit. That's the houserule. The idea of Survival not killing people is the default.
(Maybe I should repost that one in the DMing advice thread).
Would you have a problem with the Dragon eating people as the result of a Survival check? I certainly wouldn't. But, you don't get to pick and choose your dinner with a Survival check. You get food, not necessarily the food you want.
On the flip side, if the PC's are so powerful that, a dragon is now relatively a non-combat deer to them, then why not? The reason you can kill deer or rabbits with a survival check is because there is no (or at least extremely little) chance that either of these animals could kill you. So, why would you bother engaging the combat mechanics for a forgone conclusion?
So, I'd have zero problem with the Red Dragon feasting on villagers after a Survival check. But my 15th level fighter? Not too likely since that's not a fight with automatic success. My PC's certainly could, at that level, give the dragon a run for its money.
Now, killing low level PC's? Sure, but, that's the poorest form of DMing we could find. Killing PC's is ludicrously easy. Challenging them is hard.
