In the now locked thread on bin Laden's death, a poster implied that he would murder the family of a man who murdered his child. For questioning this, a private message implied that I needed to move on to the Daily Kos or Democratic Underground (partisan Democrat sites). I had thought this was a fairly non-controversial opinion on the nature of justice, that transcends political divides. Perhaps I was wrong. So is revenge against the family of someone who has wronged you justified? Is it moral? Should it be permitted by society, or are laws against vigilantism and vendetta wrong? Is revenge itself, even directly against the person who has wronged you, moral? Opinions welcome. Also, since the thread is now locked, I would welcome that poster to clarify his views if I misunderstood them.
