I don't understand the problem with the death penalty. I look at it as simply euthanasia of a subset unfit to live in society due to a clear danger. Dogs that present a danger are 'put down', why not humans? I fully understand the slippery slope nature of this attitude, I understand the impact of systemic racism, and regional politics. That is reason for the appeal process and far more than a dangerous animal gets. To me it isn't about revenge, it's about the relative security of the rest of society. I don't even care if they are so-called mentally ill. Psychology is akin to voo-doo and until the brain can be fully understood and effectively diagnosed it remains no excuse. Do we save dogs made vicious with rabies? Personally, I think the brain-washing of religion and systemic narcissism has placed humans on an artificial pedestal.
Maybe if the death penalty was applied to crimes where they arent often the result of a disadvantaged upbringing, or a moment of imflamed passion as many murders are then it would actually be effective as a deterrent.
Imagine if the corrupt shameless corporate sharks which caused the GFC had the death penalty hanging over thier heads instead of the hand slap they have gotten. Do you think the untold hardship and suffering the collapse of the economic systems around the world has caused might have been avoided if that was the sort of penalty these guys have faced?
it just seems to me that the people the death penalty affects are the least likely to be the ones who would think about it as a detterent before they commit the crime.
Plus, regarding deterrence, the murder rate is lower in states that don't have the death penalty.
