There is disagreement among Buddhists as to whether or not Buddhism forbids the death penalty. The first of the Five Precepts (Panca-sila) is to abstain from destruction of life. Chapter 10 of the Dhammapada states:

Everyone fears punishment; everyone fears death, just as you do. Therefore do not kill or cause to kill. Everyone fears punishment; everyone loves life, as you do. Therefore do not kill or cause to kill.
Chapter 26, the final chapter of the Dhammapada, states, "Him I call a brahmin who has put aside weapons and renounced violence toward all creatures. He neither kills nor helps others to kill." These sentences are interpreted by many Buddhists (especially in the West) as an injunction against supporting any legal measure which might lead to the death penalty. However, as is often the case with the interpretation of scripture, there is dispute on this matter. Thailand, where Buddhism is the official religion, practices the death penalty, as do all other countries where the majority of the population is Buddhist, i.e. Sri Lanka, Mongolia, and Myanmar, although the last has had a moratorium on executions since 1997. Moreover, throughout almost all history, countries where Buddhism has been the official religion (which includes most of the Far East and Indochina) have practiced the death penalty. One exception is the abolition of the death penalty by the Emperor Saga of Japan in 818. This lasted until 1165, although in private manors executions continued to be conducted as a form of retaliation.

The first precept of Buddhism focuses mainly on direct participation in the destruction of life. This is one reason that the Buddha made a distinction between killing animals and eating meat, and refused to introduce vegetarianism into monastic practice (see Vegetarianism in Buddhism). In Jataka, which tells stories of the past lives of the Buddha, a Boddisatva (a previous incarnation of the Buddha) actually kills someone to save another person's life, but because of this action he was no longer able to achieve enlightenment in that particular life. Therefore, few (if any) Buddhist groups issue blanket decrees against Buddhists being soldiers, police officers, or farmers (which in Buddhism is classified as a profession involved in destruction of life), and some argue that the death penalty is permissible if it is used for preventative purposes. In general, Buddhist groups in secular countries such as Japan, Korea, and Taiwan tend to take an anti-death penalty stance, while in Thailand, Sri Lanka, and Bhutan, where Buddhism has strong political influence, the opposite is true. Almost all Buddhist groups, however, oppose the use of the death penalty as a means of retribution.
