One assumes the principal acted the way he did, and it is a logical assumption. For confirmayion, one can speak with the principal. As for why hashem does things, surely people can make logical assumptions, but last I checked there was no way to confirm those assumptions. Perhaps there are people in this generation who do have ( i will call it) the gift to know with clarity and certainty why hashem does things, but, I will say with certainty they are not members of this forum.
So, go ahead speculate. Immorality, bittul torah, talking in shul, all speculation, but if it spurs you to improve in the area, go for it. Please do not project your shortcomings on the rest of the general public. That is for the leaders of the community.
