Foremost among these is that death penalty serves as a deterrent to people who intend to commit a capital offense. (Hinton, 2009). The website studyworld.com stated that death penalty is said to deter crime by putting the fear of death to people contemplating to kill someone (Studyworld.com, n.d.). It went on further to say that if a person thinks that harm will befall him if he does something wrong, then he will no longer pursue it. As mentioned in the same website, another reason why death penalty deters crime is the fact that there will no longer be a killer if he is killed already. This is applicable especially in serial killer cases.
Another major advantage of adapting capital punishment is that the penalty is justified by the crime itself (Hinton, 2009). If a person kills another person, it is but fitting that he suffers the same fate too. The criminal’s lack of respect for the value of human life does not make him deserving of respect for his own life. He has given up the concern for life when he took away somebody else’s life. As Kozinski (U.S. 9th Circuit Court of Appeals) rightly puts it, "Most of us continue to believe that those who show utter contempt for human life by committing remorseless, premeditated murder justly forfeit the right to their own life” (Prodeathpenalty.com, n.d.).
Another argument presented by Hinton for death penalty is that some people argue that the criminal’s death brings about a closure for the victim and his family (2009). It is easier for the victim (if still alive) and his family to move on if they know that the perpetrator of the crime has been duly punished.
As opposed to life imprisonment, death penalty eliminates the possibility for the criminal to commit more crimes. In life imprisonment, the criminal may be granted a parole or may even escape; therefore, may commit another crime.
Opponents of capital punishment claim that there is a danger of taking an innocent person’s
