This sort of think represents a useless and counterproductive branch of practical survival training.

1) There is no need to skin game alive. None. Never. I have killed and butchered chickens bare handed. A training session with limited utility but it shows that with some determination, training (basically understanding that it can be done) you can get a lot done with no tools other than what your born with. But there was no need to be cruel. Necks can be broken or the animal strangled.

2) Harvesting game doesn't represent a practical or efficient survival method for most people in most locations. We haven't been a frontier nation for a long time so playing Daniel Boone is usually not a practical strategy. For most people laying in a case or two of Beanie-Weenie is a far more efficient strategy.

Even the few people who are likely find themselves deep in the woods in a survival situation need to consider that time and effort spent hunting is time and effort not spent working on getting rescued or hiking out.

The only people who really benefit from hunting game as a major food source are people homesteading the forest. In which case your not concerned with survival during an emergency. Your practicing a lifestyle.

3) The idea that there is a level of blind determination and willing cruelty that gives you an advantage is simply false.

Torturing animals is indicative of a callus and antisocial personality that is highly likely to have difficulty getting along with others and are prone to escalating open-ended conflicts with other people even when things are going well. During a high stress situation this sort of immature, antisocial, paranoid, angry and unfeeling personality will tend to cause resentments and conflicts that distract from and interfere with practical efforts. Exactly the sort of loose-cannon personality that becomes both a hazard to themselves and those around them.

4) Discounting the problems that such personalities are prone to in a survival situation these sorts of public demonstrations plays into the stereotype of practical survival and preparedness as a macho boy's club full of camouflage-clad gun worshipers and emotionally stunted angry Peter Pans.

This 'training' and video is exactly the sort of macho stunt that gives survival a bad name.
