answer:You were watching the movie version of **** of the Flies and thinking it was a documentary. Because you were young at the time, you conflated the movie with a documentary in your mind. What you’re describing are scenes directly from the movie. This was a work of fiction. There were no real-life cases of events like that happening. William Golding was an excellent writer with a great imagination. But what he wrote (upon which the movie was based) was totally a work of fiction predicated upon what would happen if all societal constraints and rules were removed from a group of children in an isolated environment. His FICTIONAL conclusion was that they would revert to savagery. But there is no documented case of this happening in real life. You thought you were watching a documentary when, in reality, it was the movie. Childhood memories are not exactly known for accuracy :)
