The death penalty fulfills a preventive function, but it is also very clearly a form of revenge. It is an especially severe form of punishment because it is so final. The human life is ended and the executed person is deprived of the opportunity to change, to restore the harm done or compensate for it.

In order to become prosperous, a person must initially work very hard, so he or she has to sacrifice a lot of leisure time. Similarly, the Buddhist is willing to sacrifice immediate comfort so that he or she can achieve lasting happiness.
