Thinking a lot about shame and shaming this week, its function in society and its inevitable misapplication

I mean, shame to disincentivize socially undesirable behavior makes sense. But how much of it becomes about the shamer feeling good? About themselves & their own choices?

Maybe the two are inextricable. I dunno. But online shaming seems to be one of the more popular quarantining activities right now and now maybe this thread is itself engaged in it?
