Certain unwise, careless, or as we say, ‘self-destructive’ actions often bring in their train consequences unpleasant to the agent according to natural law. If an agent through folly or otherwise acts in a way which shows that he has ignored or forgotten predictable or possible consequences people will say ‘it serves him right’, meaning ‘he ought to have foreseen that’. Sometimes they will even say ‘he got what he deserved’. For these reasons such consequences can be called punishment, or a kind of punishment.
