The threat that the beast makes to Simon is that all of the boys will murder him. Lord of the Flies was written by William Golding.
The beast tells Simon that it is a part of him, and that it suggests that it is within every human on the island, foreshadowing the idea that the true threat lies within themselves and their own actions.
Simon does not believe Sam and Eric's story about the "beast" being a physical threat. He understands that the beast is a manifestation of the boys' fear and inner darkness, rather than an external monster. Simon tries to convey this understanding to the group, but is ultimately killed before he can do so.
In The Lord of the Flies, Jack explains Simon's death to the boys who are with him by convincing them that the beast killed him. He even tries to make himself believe this lie.
Simon told the other boys at a meeting that perhaps there was a beast and that the beast was just themselves. This indicates that Simon does not believe that the beast is a creature with wings, claws and teeth but that it is simply the boys themselves. The beast is just the desire and capacity to do evil which is within us all. Later in the book, after Samneric report actually seeing the beast, I quote... "However Simon thought of the beast, there rose before his inward sight the picture of a human at once heroic and sick."
No, Jack did not believe that Simon was the beast in "Lord of the Flies." He mistook Simon for the beast during a frenzied dance in the forest, but later realized his mistake and Simon's true identity.
He knows that the beast is inside of them. In other words that the beast they believe is out there is actually the evil inside of them.
Simon's comment was about the beast. He suspected that the beast was not an animal and obviously didn't believe that it was a ghost. This left only one remaining possibility, that there was no beast. Simon believed that the beast was simply a product of the boy's own imaginations. The beast only existed in their own minds. However there was a deeper reasoning to Simon's comment. Simone suspected that the beast wasn't just a product of the boys' own imaginations but was actually the boys themselves. It was the boys themselves who were the 'beast,' capable of hurting, of killing and of committing acts of evil.
Simon
Simon doubts the existence of the beast because he possesses a deeper understanding of human nature and recognizes that the true source of darkness lies within each individual. He represents the voice of reason and spirituality in the novel, contrasting with the other boys who are consumed by fear and violence. Simon's introspection and connection to the natural world make him more inclined to question the existence of a physical monster, as he sees the real threat as the inherent evil within themselves.
Simon was mistaken for the beast in "Lord of the Flies". He was killed by the other boys during a frenzied tribal dance on the beach.
Simon.

Simon is the only character who realizes that the beast doesn't exist and that the true beast is within themselves.
