I wouldn't call the villagers stupid. They're just in that same mindset as Puritan Christians (or most Christians at that time for that matter) would burn witches (usually innocent old women, though young women were targeted as well) for the most ridiculous reason imaginable. I'll use a statement previously used on the Theory Blog. "They put 1 and 1 together and got 3."

While we can't glean any details from gameplay, it would be natural to assume that the Moga villagers had some type religion greatly connected to nature, like the druids, and that they were very religious, using the religion to try to explain absolutely everything in the world, whether it actually makes logical sense or not. That they say the Lagiacrus you previously fought is the same one you fight later is evidence of this, because they think that the Lagiacrus returned to get its revenge on the hunter who cut off its tail or broke its horns or whatever. It's unlikely that the Lagiacrus is sentient, so the theory it's getting revenge is nothing but conjecture based off conjecture.
