Faith, at times, can indeed be a terrifying thing.
For the more rational individuals, they were able to make their own judgements through the scene that had just unfolded. The mysterious figure did not seem like the so-called evil demon; rather, it was the worshiped divine spirit whose actions were more akin to those of an evil heretic.
