Is capital punishment a deterrent t

Is capital punishment a deterrent to crime? At the outset, we should acknowledge that the answer to this question should not change our perspective on this issue. Although it is an important question, it should not be the basis for our belief. A Christian's belief in capital punishment should be based upon what the Bible teaches not on a pragmatic assessment of whether or not capital punishment deters crime.


That being said, however, we should try to assess the effectiveness of capital punishment. Opponents of capital punishment argue that it is not a deterrent, because in some states where capital punishment is allowed the crime rate goes up. Should we therefore conclude that capital punishment is not a deterrent?

First, we should recognize that crime rates have been increasing for some time. The United States is becoming a violent society as its social and moral fabric breaks down. So the increase in the crime rate is most likely due to many other factors and cannot be correlated with a death penalty that has been implemented sparingly and sporadically.

Second, there is some evidence that capital punishment is a deterrent. And even if we are not absolutely sure of its deterrent effect, the death penalty should be implemented. If it is a deterrent, then implementing capital punishment certainly will save lives. If it is not, then we still will have followed biblical injunctions and put convicted murderers to death.

In a sense, opponents of capital punishment who argue that it is not a deterrent are willing to give the benefit of the doubt to the criminal rather than to the victim. The poet Hyman Barshay put it this way:

The death penalty is a warning, just like a lighthouse throwing its beams out to sea. We hear about shipwrecks, but we do not hear about the ships the lighthouse guides safely on their way. We do not have proof of the number of ships it saves, but we do not tear the lighthouse down."(1)
If capital punishment is even a potential deterrent, that is a significant enough social reason to implement it.

Statistical analysis by Dr. Isaac Ehrlich at the University of Chicago suggests that capital punishment is a deterrent.(2) Although his conclusions were vigorously challenged, further cross- sectional analysis has confirmed his conclusions.(3) His research has shown that if the death penalty is used in a consistent way, it may deter as many as eight murders for every execution carried out. If these numbers are indeed accurate, it demonstrates that capital punishment could be a significant deterrent to crime in our society.

Certainly capital punishment will not deter all crime. Psychotic and deranged killers, members of organized crime, and street gangs will no doubt kill whether capital punishment is implemented or not. A person who is irrational or wants to commit a murder will do so whether capital punishment exists or not. But social statistics as well as logic suggest that rational people will be deterred from murder because capital punishment is part of the criminal code.
