ACLU said:"It [capital punishment] is immoral in principle, and unfair and discriminatory in practice [...] No one deserves to die. When the government metes out vengeance disguised as justice, it becomes complicit with killers in devaluing human life and human dignity.
In civilized society, we reject the principle of literally doing to criminals what they do to their victims: The penalty for rape cannot be rape, or for arson, the burning down of the arsonist's house. We should not, therefore, punish the murderer with death... Capital punishment is a barbaric remnant of uncivilized society."
There are a few reasons I abhore the death penalty. I think the argument against the death penalty has been made many times but to mention a few points. It does nothing to improve social welfare and in fact most likely harms social welfare.
The justice system used to dole out death sentences favors the rich over the poor.
It is vengeance disguised as justice.
The fact that innocent people have been executed should be enough for most people to understand we are not perfect in our ability judge and should not be taking our best guesses on death sentences. Despite all of our checks and balances... innocent people are still legally executed.
At some point violence has to stop. More killing is not going to make anything better. It won't bring anyone back from the dead and won't right any wrongs. Its just killing for the sake of killing. It doesn't appear to be a credible deterrent either.
ACLU said:"[T]here is no credible evidence that the death penalty deters crime more effectively than long terms of imprisonment. States that have death penalty laws do not have lower crime rates or murder rates than states without such laws. And states that have abolished capital punishment show no significant changes in either crime or murder rates.
The death penalty has no deterrent effect. Claims that each execution deters a certain number of murders have been thoroughly discredited by social science research. People commit murders largely in the heat of passion, under the influence of alcohol or drugs, or because they are mentally ill, giving little or no thought to the possible consequences of their acts. The few murderers who plan their crimes beforehand -- for example, professional executioners -- intend and expect to avoid punishment altogether by not getting caught. Some self-destructive individuals may even hope they will be caught and executed.
As far as no one being right or wrong... I believe supporting the death penalty is wrong. I realize most of the united states still supports it and that has to change in my opinion. There are many states that have done away with it and many parts of the world where it is abolished.
