Death punishment is a highly controversial and emotional issue about which most people seem to have strong arguments. In United States, controversy over death punishment began in colonial periods when, against the consents of the English Crown, some settlements enacted only a few capital laws. Soon after the War for Independence and the adoption of the Constitution, America''s death penalty debate started in earnest. Death punishment is a subject that must be addressed with today''s violent society. The death penalty provides the necessary punishment and deterrent for criminals in America whereas the possibility of executing an innocent is the main subject matter for anti-death penalty campaigns.
The death penalty is necessary as it deters murder by putting the fear of death into ''would be killers''. A person is less likely to kill someone, if he or she knows its consequences onto him /her. Another way the death penalty deters murder, is the fact that once the killer is dead, he will not be able to kill someone again. Since society has the keen interest in preventing murder, it should use the maximum punishment available to prevent murder, and that is only the death penalty. If murderers are sentenced to death and executed, potential murderers will think twice before killing for fear of losing their own life. Simply speaking, this is a form of incapacitation, similar to the way a robber put in prison is prevented from robbing again on the streets. Vicious murderers must be killed to prevent them from murdering again, either in prison, or in society.
Most supporters of the death penalty feel that offenders should be punished for their crimes, and that it does not matter whether it will deter the crime rate.
Supporters of the death penalty are in favor of making examples out of offenders, and that the threat of death will be enough to deter the crime rate, but the crime rate is irrelevant. If even one life is saved, for countless executions of the guilty, it is a good reason for the death penalty. The execution of convicted offenders expresses the great value society places on innocent life. The law should treat a killer simply a killer no matter whether he/she is juvenile or not. Similarly death penalty is way to give justice to deprived family whose member had been killed by killer and it should not be attached with the debate that whether it is helpful to reduce crime rate or not. It is against the justice. As far as crime rate control is concerned, there is a need to work on social tendencies prevailing in society as origin of crimes would be found due to disturbance in social values but it does not mean that making it a baseline death penalty should be opposed.
Finally it is necessary that whole issue must be seen in its right context - a killer indeed is a killer of whole humanity and he/she does not deserve a mercy or human rights protection as when he/she killed other person he/she has lost an entitlements reserved for human beings and his/her status in society is a killer - of not a single person but whole humanity.
