Harmful on Purim

The accepted understanding is that anyone who causes harm for the sake of joy is exempt, as it is written in the Shulchan Arba about young men who cause harm at the joy of a bride and groom. This is not unique to Purim. And yet the feeling is that this is not about forgiveness in the simple sense, but rather that the Sages have determined that forgiveness is granted, at least at the joy of a mitzvah. As for the temple, the rabbis have determined that it is a sanctuary, and even there, in my opinion, there is no mention of the condition that the temple itself is a gift that will apply to the Sages' consent. This is a condition that the Torah is a gift, that the sanctifications are conditional on the consent of the Sages. Evidence for this must be provided, and so on. According to this, it doesn't matter whether you are forgiven or not, of course. But I once wrote that I have a feeling that there is some deeper halachic trend on Purim, to allow us to commit transgressions. In terms of the future, all the books are null and void, except for the Book of Esther. All the holidays are null and void, except for Purim. There is something about Purim that is above the halachic, and there is a trend among the poskim to allow permissions on Purim that go against the halachic. That is why the poskim wrote quite a few permissions (to wear women's clothing, to have rabbinic marriages, and so on. I think the primary source is in the Responsa of Mahary Mintz). My argument is that the sages have a trend to instill in us the idea that even halachic law is not the end of the road, but rather that it comes to serve something higher, and therefore one day a year we act against it (albeit cautiously. That is why they only allowed rabbinic marriages). According to this proposal, it is also irrelevant whether you forgive or not. But according to your assumption that it is indeed accepted by the jurists that this is a forgiveness, it is clear that if people today do not forgive, this law is null and void as a Kafra Daraa. This is a factual claim and has no sanctity or authority in it. It all depends on the factual situation.
