Deterrence or Retribution Theory of Punishment?

(Kenneth Anderson)

From the Guardian:

Monks at the 15th century church of San Salvatore al Monte, which was a favourite of Michelangelo, were irritated when a rare and expensive bible disappeared from the lectern, and they flew off the handle when a replacement bible donated by a worshipper also went missing and within a few hours.  In a note, pinned up in full view of worshippers, the monks say they hope the thief sees the error of his ways. But in case he does not, they add: "We pray to God that the thief is struck by a strong bout of the shits."  This turn of events will, they hope, "encourage him to carry out no further thefts".
