At times, there is a thin line between civility and depravity. Once crossed over, there is no coming back to normalcy. What one seeks and accomplish, doesn't necessarily satisfy the yearning. I vote no on the death penalty, but yes on justice. Each has a price to be paid, the difference is the exchange rate.
I think we are all two people. If someone took my son's life, I would not only kill them, but probably make them suffer tremendously. That is the "individual" in me. And this is also the reason why I would never want to be on the jury, since allowing a relative of the victim to form part of a jury would make it impossible for anyone, including me if I were ever falsely accused, to get a fair trial. That is the "citizen" in me.
So, to answer your question, as much as I would take away the life of someone who harmed someone I loved, I am glad I live in a country where it's the citizen's perspective that prevails. There is no merit in killing someone, it costs more that keeping them in prison for life and it adds to the already high level of desensitization and apathy prevalent in our society.
I used to be for it, but now am against it. I suppose I am turning into one of those "bleeding heart liberals" that many despise. (And no, I have never lost a loved one, friend or even acquaintance to a murderer.) I suppose MAYBE, if one is on death row and chooses to die with "dignity" because s/he is sick and tired of a futile life behind bars, then it should be allowed. I have a hunch though, that back in the "Good ol Days" there were quite a few put to death innocently or because of legal faux paux that would never be tolerated today. But I will admit, I am NOT one of those holding candles out at San Quentin to protest either. I'm thinking: "Better him than me." I'm pretty sure there are plenty of cops back in the "good ol days" that sent an innocent or "scumbag" that DID NOT do the crime they went to death for. So maybe all the pro death penalty people can smile over that. Still, I would like to think that even as a "scumbag" facing lethal injection I would at least like to be executed for the "right" crime if you can dig what I'm saying here.
The answer is obvious: it should be abolished. Man's wrongdoing can't be attributed just to himself. Life path he has taken so far makes what he is now. A criminal would have been a different one if he had born in other family, got along with other friends, or not been discriminated by his pals in school.
