What wild animal would stand still and watch while a human is being eaten alive?

No carnivorous animal would stand idly by and watch as a meal is consumed by others. Actually, I take that back. Vultures/buzzards will circle above and watch the action unfold. If the kill is successful, they will wait patiently until the predators have reaped the reward of their effort. They will happily pick over the leftovers, virtually cleaning the bones of any remaining soft tissue. That is their reward for their patience.

Most other herbivores and omnivores who are more likely become a meal themselves than gain from the spoils of the kill will likely instinctively scatter from the scene.

In nature, animals want to avoid capture, want to eat and want to mate. If the scenario you described does not satisfy any of those goals, they aren't going to be interested in what is happening. They certainly have no reason to intervene.

Right, Luke, more about pit bulls (which you still can't spell) and wild creatures and sea creatures ripping your testicles off while your dog watches.

All wild animals would stand still and watch while a human being is being eaten alive.

They would also stand still while the said pit bull was ripping off your testicles.

On the autism spectrum, I'm guessing Aspergers.

Do your own research.

Watch Nature on PBS, so you can see how different animals act around predators.

Some hang around for leftovers, while others get as far away as possible so they aren't next.

hopefully none of thenn, sonne of thenn nnight even try and help

Not many would just stand there.

Carnivores would hear the crunching and go to try to steal some food.

Prey animals would hear the crunching and run away from the carnivores that are eating.

All of them.
