The principal, equally as shocked, gave an apology for originally inviting the group to the school.
You have to wonder about the competence of the principal, since the agenda of "You Can Run but You Can't Hide" as well as JYP is pretty well known and clearly stated by them in all of their literature and even their website.
The issue in your example is not in the agenda of the speakers, but rather the absurd statement that the principal was surprised or shocked. For that to be true the principal was either woefully negligent in doing even a cursory diligence or dumber than a red brick. It is far more reasonable that the agenda was known beforehand but that the principal misjudged what the reaction of the students would be.
As to the question asked, which seems unrelated to the example you used, you asked:
Is religious fundamentalism bringing our moral system down faster than Agnostic beliefs can rebuild it?
I am curious how you think the example you cite has anything to do with morality?
