Why should the death penalty be abolished?

In fact, some people say that the abolition of the death penalty is mainly due to its irreversibility. Since the 1990s, there have been more than a dozen death penalty cases in China, and a few of them have been given suspended sentences. Most of them are unjust cases discovered after implementation. Although they have been rehabilitated and compensated by the state, they cannot be resurrected after death. It can't be abolished at this stage. It can only be said that it is strictly controlled and the death penalty should not be abused. If abused, it will lead to social unrest. In the case of the death penalty in Hugue Gilletu (including the circumstances of extorting a confession by torture), 27 people were held accountable (severe warnings in the party and administrative demerits), and Feng Zhiming led to another duty crime case, and was sentenced to 15. Although Nie Shubin's death penalty injustice case has been rehabilitated, there is no accountability. Family members are applying for state compensation, demanding strict accountability for those involved in the injustice case. For death penalty cases, for the deceased and their families, the public prosecution law is disastrous. No matter how much compensation and accountability the state has, people's lives can't be saved. The essence of the death penalty is also murder, only murder in the legal sense, not murder in human nature. We can't stop legal murders, nor can we report legal murders.
