I've tried to find some well established opinions on both sides of the coin, I have some pretty strong opinions myself which I'll hold in check for the moment.
I'll post the opinions on a every other order starting with pro death penalty first;
Quote
Bruce Fein, JD, General Counsel for the Center for Law and Accountability, in an American Bar Association website article titled "Individual Rights and Responsability - The Death Penalty, But Sparingly" (accessed June 17, 2008), offered the following:
"Abolitionists may contend that the death penalty is inherently immoral because governments should never take human life, no matter what the provocation. But that is an article of faith, not of fact, just like the opposite position held by abolitionist detractors, including myself... The death penalty honors human dignity by treating the defendant as a free moral actor able to control his own destiny for good or for ill; it does not treat him as an animal with no moral sense, and thus subject even to butchery to satiate human gluttony. Moreover, capital punishment celebrates the dignity of the humans whose lives were ended by the defendant's predation."

Thurgood Marshall, JD, late Justice of the US Supreme Court, in a June 29, 1972 Furman v. Georgia concurrent opinion, stated:
"[Capital punishment] violates the Eighth Amendment because it is morally unacceptable to the people of the United States at this time in their history. In judging whether or not a given penalty is morally acceptable, most courts have said that the punishment is valid unless 'it shocks the conscience and sense of justice of the people.' Assuming knowledge of all the facts presently available regarding capital punishment, the average citizen would, in my opinion, find it shocking to his conscience and sense of justice. For this reason alone, capital punishment cannot stand."

Eliot Spitzer, JD, Former Attorney General and Governor of New York, in a June 13, 2000 hearing on "Postconviction DNA Testing of New York State Attorney General Eliot Spitzer Before the Senate Judiciary Committee," available at the judiciary.senate.gov website, stated the following:
"Our federal and state constitutions are replete with rights we afford the accused -- the right to notice of charges, the right to a speedy and public trial, the right to confront witnesses, the right to counsel, the right against self-incrimination. We as a society have made a profound commitment to avoid punishing the innocent. This is particularly important to those of us who support the death penalty in appropriate circumstances. We have determined that there are instances when the crimes are so egregious that society’s ultimate punishment -- the death penalty -- may be appropriate. But the imposition of this punishment can be justified only if we make full use of all available tools to aid in the determination of guilt or innocence."

The United Nations General Assembly, on Nov. 1, 2007, in an 104-54 vote to which the US was a primary opponent, adopted a non-legally binding moratorium on the death penalty:
"The General Assembly... Recalling also the resolutions on the question of the death penalty adopted over the past decade by the Commission on Human Rights in all consecutive sessions... in which the Commission called upon States that still maintain the death penalty to abolish it completely and, in the meantime, to establish a moratorium on executions... Considering that the use of the death penalty undermines human dignity, and convinced that a moratorium on the use of the death penalty contributes to the enhancement and progressive development of human rights, that there is no conclusive evidence of the death penalty's deterrent value and that any miscarriage or failure of justice in the death penalty's implementation is irreversible and irreparable... Welcoming the decisions taken by an increasing number of States to apply a moratorium on executions, followed in many cases by the abolition of the death penalty,
1. Expresses its deep concern about the continued application of the death penalty;
2. Calls upon all States that still maintain the death penalty to:
(a) Respect international standards that provide safeguards guaranteeing the protection of the rights of those facing the death penalty... (c) Progressively restrict the use of the death penalty and reduce the number of offences for which it may be imposed; (d) Establish a moratorium on executions with a view to abolishing the death penalty..
I know it's a wall of text but I tried to keep the quality of the quotes a equal as I could, I would really like to read your opinions about this issue.
