Throughout history, humans have applied various cruel techniques for punishing wrongdoers in their societies. In the ancient times, societies used various methods to kill persons accused of heresy, adultery, theft, robbery, murder and other forms of deviance. However, with an increasing trend towards recognition of human rights and reduction of cruel, unfair and unreasonable pain, societies throughout the world have increasingly attempted to abolish death penalty, especially when dealing with individuals accused of various offenses such as adultery, heresy and robbery (Londono 109). In fact, capital punishment has been on the decline in the past five decades. Nevertheless, death penalty in cases of such crimes as murder has remained applicable in various nations, despite the existing evidence that it is not only an unfair way of dealing with offenders, but also a violation of human rights, God’s law and human dignity. The US is one of the few countries in the modern world that have resisted the move towards abolishing capital punishment through death penalty (Londono 21). In fact, death penalty is an old way of dealing with crime, which the US has borrowed despite the presence of the knowledge that death penalty is an archaic and barbaric technique. Thus, the US should abolish this penalty because it is not only medieval, but also crude, ineffective, costly and unjust. Yet, the country has always been presenting itself as the most democratic country in the world. In addition, the US claims to posses one of the best laws and mechanism that respect human rights. Despite this, the US has been applying the law that legalizes killing of offenders as a way of punishment, yet the Eighth Amendment prohibits cruel and unusual punishment (Haines 12). Evidently, the purpose of having a national and state criminal law is to deal with the problem of crime and ensure the society enjoys peace and harmony. The law aims at dealing with crime through rehabilitating offenders and incapacitating hardened offenders. Incarceration was initially designed to punish these individuals. However, the modern American incarceration plays most of these functions other than punishment. In fact, prison life is an important and effective way of rehabilitation, incapacitation of hard criminals and alleviation of crime in the society. On the other hand, death penalty does not give these individuals a chance to change their behavior and adopt better relationships with other people (Lambert, Clarke and Lambert 57). In addition, death penalty was important in eliminating hardened criminals who kept on escaping from prisons to cause harm in the society. However, with better prisons, equipment and methods, escaping from American prisons is no longer possible. This means that life imprisonment is more effective than death penalty because it incapacitates the hardened criminals while at the same time providing them with a chance to change their behavior (Lambert, Clarke and Lambert 117). The philosophical consequence of death law does not prove that the act of killing offenders is something related with criminal justice. Rather, it has been shown that it is based on some other preferences that allow the society to sacrifice justice to achieve deterrence. It is evident that death penalty favors deterrence. However, it is no better than other penalties. For instance, it has been shown
