Yes, I do support using the death penalty in sentencing in the court system in the United States. If someone is proven to have taken someone's life, they deserve the same fate. If an innocent life is lost at the hand of a criminal, they should be killed the same way. Maybe it would help others not do the same thing.
The death penalty is a strong deterrent for crimes potentially impacting innocent lives. While it cannot prevent all homicides, it can deter some of them. At the same time, keeping a convicted murderer in prison for life places a significant financial burden on the public, especially with the current laws protecting prisoners. For those criminals convicted of deliberately taking an innocent life, I think the death penalty is a suitable punishment.
There are criminals that cannot be rehabilitated and should never be allowed to go free, (particularly serial murderers and sex offenders). However, "an eye for an eye" should not be applied in these situations. Regardless of religious beliefs, putting someone to death, no matter how bad the crime is, is a form of "playing god". Criminals who cannot be rehabilitated should serve life sentences without the possibility of parole, and be required to work in a highly supervised setting on jobs that benefit their community.
No, I believe the death penalty should not be used for sentencing in the court system. It is completely hypocritical of our courts to deem murder illegal and then turn around and commit it themselves. As Gandhi once said, "an eye for an eye makes the whole world blind." The punishment of life in prison can be a worse fate for many of those people facing the death penalty. Though this is my position, the argument that it is necessary does have its merits, because it is a good deterrent for many would-be killers.
I do not believe the death penalty is the option for any crimes no matter how severe. The death penalty is inhumane and in the modern world that we live in it is inhumane. There is also the chance that the prisoner may not in fact committed the crime they are accused of, which has happened a few times in recent years. If there is even a one percent chance that some one is innocent of a crime it would be a crime to have them put to death by a court. Also spending ones life in prison is a harsh enough punishment and can even lead to people reforming their previous bad behaviors. These are a few of the reasons why I do not support the death penalty.
