You can argue whether or not the death penalty equates to a justified killing. Those who support the death penalty argue that their justified killings are the appropriate response to the convicted individual's alleged murder.
Your question is stated in an interesting way: it seems to be a rhetorical way to ask about capital punishment, as though you are pointing out that capital punishment inherently makes no sense. Now, if you are a citizen of a democratic nation and you are posing that question to other members of your own nation regarding the laws and punishments in your own nation, then it is your right and even your duty to do so. Democracies only really work when their citizens stand up for what they believe. In the case of making laws and punishments for violations of laws, a government has a difficult job to do. In a lot of cases, not everyone will agree with the laws the government has made.
A government has to decide what kinds of laws it actually has the right to make and what things are proper punishments for breaking those laws. An important thing to remember when you are wondering about how laws are made in a democratic nation is that a democratic government makes laws on behalf of its citizens. As a citizen, it is helpful to ask yourself "If I was in charge, what kind of law would I make." If you were making laws against murder (because you feel it's important to have a law against murder) what would you do to keep people from murdering? Some of our lawmakers have decided that a very harsh penalty might keep some potential murderers from killing. The knowledge that the punishment for murder is being executed is intended to make a potential murderer stop and think before he or she commits an act of murder.
In general, capital punishment does not serve as a deterrent. It does, however, completely resolve the issue of recidivism.
