What do you think is the moral lesson of "The Minister's Black Veil"?

I think the sin of hypocrisy shines through here. People have sins rattling around in their closet, so to speak, but often try to appear pious of guiltless. People need to be true to themselves and God. Such is the case in Mr. Hoopers congregation. The revelation of sins leaves one open to the judgments from their fellow parishioners. So, when Mr. Hooper dons his veil, each parishioner freezes and rebukes the priest conscious of their own sins.
