No. They don’t regret lying. In fact that is a big part of their modus operandum; to openly lie, to make the lie a truth, and to humiliate you by forcing you to keep your mouth shut and accept the lie as a truth.
It is effective up until the moment a critical mass of people say ”enough is enough, you are no longer allowed to lie, to decieve and humiliate us. From now on you will suffer the consequences in a very unpleasant way. You will have to pay”. nostr:note1dpgdamzts2w7jymgvmtglm2qfrpn8dluqnsacryrnhdakqmjszjswem590
