And how does this relate to the matter at hand?
Logic. Bentham's Utilitarianism suggests that one attempt to do the least harm to the least number of people. Ideally, we might be able to do no harm. But sometimes, like at the moment, harm seems to happen no matter what, and then we have to choose between the options we know now, to avoid as much harm as we can now, while we develop better solutions in the fullness of time.
And what is the downside to removing it? A minor reduction in deterrence?
If that's all it will cause, then yes. But how do you actually know how much of a reduction it will cause? You want to guess, and hope it works? Is that being logical? Provide a solid argument, and cross-check by the available data for every relevant case.
Who may very well be innocent. One cannot undo an execution if later evidence exonerates the dead party.
No. You really can't. All courts do at the moment, is award them some money. How would you like to get a million dollars for spending the next 5 years in prison? I doubt you would.
And how is the prison system relevant, here? If you're trying to appeal to 'the greater harm,' then you've committed a logical fallacy,
Never heard of Consequentialism and Utilitarianism?
and if you're trying to say that millions of people are convicted of murder and would therefore flood the system if imprisoned, then your data are wrong.
I wasn't. I was saying, that right now, millions are in prison for crimes whose details exclude death row, and for many, it would have been easier for them if they'd done those crimes, and also for others who never did that or any other crime. There is a huge motive in many situations for murder. There is also a large deterrant for doing murder on any one day. Diminish the deterrant, and you diminish it for not just those on death row, but for everyone, for every day. Statistically, you increase the chances by 300 million for the USA alone, and for every subsequent day. This raises the average yearly death rate.
With those types of numbers, the deterrant would have to be below 1 in 1 billion, for it to not cause at least one more murder a year. To be below 1 in 1 billion, would mean that only 1 in a billion murderers would avoid killing to escape the possibility of the death penalty. That's awfully low for such a high cost in people's perceptions.
Besides, that is linked to the value that one places in life, that is one of the axioms for abolishing the death penalty in the first place. Lower the value on individuals not getting the death penalty, and you lower the value for banning it in the legislature.
Argumentum ad-hominem and Begging the Question. Who cares how the people on either side of the point feel?
It's important data. There are lots of situations when we get data from the other side, that with it, we get an accurate answer, and if we ignore it, we get an inaccurate answer, or even a very wrong answer. The consequences are often if one makes beneficial or harmful choices in one's life.
Your arguments do not support your thesis. Your first paragraph isn't really relevant (unless we're building our moral system up from nihilism) your second paragraph is full of logical holes, and your third paragraph is based upon the assumption that the death penalty is a good idea and argues against the people involved.
Wrong on all counts. I never said that the death penalty was a good idea. I wasn't even suggesting that it's better to keep it.
I was pointing out that it seems that when it comes to the issue, it's sophisticated and complex, and requires much consideration, before deciding, and so even those that might want to keep it, have enough of a basis to form an opinion, even if they've not checked the figures completely.
I also didn't point this out. But, while we are here: Since these people have enough to form an opinion, dismissing their opinions, will just give them the impression that people who are against the death penalty are not interested in reason or helping to diminish harm, and then many will oppose the ban, in the belief that they are fighting an unjustified and irrational law, that would increase murder. You can't expect people to not want to keep fighting that, until they get their way. They'll never get tired. They can't. Morals don't get tired. So they'll keep fighting, no matter what. If some leave, then others will join. If you want all these conflicts in your country to cease, then you're gonna have to learn to make these people think that you ARE taking them seriously. It's your choice what you want out of life.
