The endless hordes of goat is the representation of general public in the world of Umineko or in our real life, they all tried their best to solve the mystery with some even use nonsensical explaination that is borderline fantasy, and when the truth completely failed their expectations or theories, they will crush it with all cost.
That is why Golden Beatrice theory exist, when it clearly showed that the island explodes through Kinzo's grandfather clock with Eva being the only survivor.
