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.
Dalai LamaTry to improve. Don't expect too much, but don't feel discouraged either; keep up your enthusiasm; you will make progress.
