An apology is useless if it is not accompanied by a change in behavior. Actually, worse than useless as it is an insult. I know what I am doing is wrong but I am not changing. Large public apologies are performance art.
Yes, and audiences love performance art. They don't even really hate the actor for what they did, they enjoy the vengeful feelings i guess. Everything is molded to please the public.
And as long as the public is not incredibly angry, they'll mostly just quietly go along with it, because it's not worth fighting against. But they're not the source.
It's manufactured forgiveness.
