Asked by my kid (albeit less fleshed-out than the way I'm presenting it here):
One should rather submit himself to be burned alive than cause another to blanch in shame in public, according to Sota 10:2. Tosafos there seem to take it as halachic fact, but, even if not, it seems at the very least to be a moral equivalence: causing another public shame is on a par with being burned alive. (Imagine how bad being shamed publicly must be!)
How then — at least in a case of an act of nezek that occurred in public — can the courts possibly evaluate boshes, the monetary damages for embarrassment, as some finite amount of money? It would seem it should be an inestimably large sum of money: the act committed by the tortfeasor is as bad as being burned alive!
