What is fair? What is justice?

What is an appropriate punishment for the crime? Who says so?

Crimes and their punishments have differed as widely as the societies that defined them and through time. In Sparta, citizens could be whipped for being too fat. In Rome, men and women who had not married by the ages of 25 or 20 respectively were fined. In England, it was a capital offence to rob a rabbit warren, cut down a tree, marry a Jew or deface Westminster Bridge. In Singapore, up until recently, the importation or distribution of chewing gum was punished by a fine of up to $10,000 or 12 months imprisonment.
