Can a person truly not care what an entire society has to say?

Can a person truly not care what an entire society has to say?

What I mean is if a person is guilty of being despicable and nasty. Sure that person can bark all they want and not care what the 1-person audience or even say 100 people have to say.

However if every news media channel talks about it and shows some sort of resent or confronts them, criticizes them to shame them and embarrass them by publicly displaying their logical fallacies….would they still not care what others have to say?

I can imagine a person wrongly convicted of a crime to have a strong headed mindset (although not always) but what about a person who is guilty of something despicable or shameful ( I am aware they might not feel shame for it)....would they not feel embarrassed and either give up or “not meet the eyes” of others for it? Will they feel shame about it?
