> Humiliating someone publicly is a very good way to destroy ones ego/dignity and deter anybody else from committing anything similar in the future.

Just out of curiosity, do you have anything to support this? My experience as a lawyer would tell me otherwise, and that by destroying someone's ego will rather make them more brutal, apathetic and nihilistic than any kind of rehabilitation. But that's just my data sample of one, so I'd love to understand more.
