An eye for an eye?

       I'm sure there are kids who start their college essays with "An eye for an eye makes the whole world blind." This saying, attributed to Gandhi, is supposed to be saying that world peace is something that everyone should be interested in achieving. As a man of peace, and someone who was fully committed to helping others, Gandhi is certainly who makes a good role model for morals. There must be a line drawn in the sand though, there are simply some people in this world who want to watch the world burn. No matter how many people they hurt, no matter how guilty they should feel, they'll never get it. If not put away, or in this case put to death, they would just keep hurting. When that is the case, the saying "an eye for an eye makes the whole world blind" simply does not cut it.
       Many people who are against the death penalty in the United States will use that saying as an argument stating that revenge should not be the answer. I would like to be able to say that revenge is bad, or that it is unhealthy to want it, but I simply don't think that's true. When someone is murdered in a brutal way, the family will be upset, and chances are they will want revenge on the person who committed the crime. This is not wrong, and although it "may not be the answer" it may bring some kind of closure for them. There are certainly cases where the family is still not satisfied even after the murderer has been put to death, but after that there is nothing else that can be done.
        I'm not arguing that the death penalty is right and just, and I'm certainly not arguing that there are no flaws in the system -that much is blatantly clear- I am however saying that there is no reason to abolish it completely. I believe that sometimes it is necessary for someone to be sentenced to death. They should not be allowed to live on this Earth anymore. In very specific cases of course. Some may disagree, and I'm not quite sure that I have the plan right in my mind. I would make it so someone would only be eligible for the death penalty if they killed more than one person (possibly even more than two or three, I'm not sure on the number, and I'm not qualified to make that kind of judgement). There are cases where the crime is too terrible. Too gruesome. The death penalty should only be reserved for those that are atrocious and the worst of the worst.
