I never thought I would a "bleeding heart liberal" like you JanH! I am a Libertarian by philosophy, but that's irrelevant. I do not support the Libertarian party, nor many of their platforms.
For almost my entire life I've been "for" the death penalty, and it's only been in the last year that I've given serious thought to the matter. I've concluded that all my reasons for supporting it were irrational: it makes the victim's survivors "feel good" or "have closure"; it guarantees that the murderer will never be in prison and be released should laws change in the future; the severity of the punishment fits the severity of the crime. These reasons are ALL irrational.
Our society does not torture and rape rapists who've done the same thing to their victims, does it? We don't shoot people in the leg who have shot someone else in the leg. We don't beat the beaters and we don't run over with cars the vehicular man-slaughterers.
If we kill the killers, then we are being inconsistent and hypocritical.
The more evidence I see about DNA tests absolutely confirming the innocence of people who've been on death row for decades, the more I'm convinced we are not qualified to issue such a permanent and irrecovable punishment.
But my BEST argument against the death penalty is that it is EXACTLY the same penalty that "Jehovah God-of-the-Bible" enjoys the most. I don't like "Jehovah God-of-the-Bible" and don't want to emulate him. Whatever he has done has always been proven to be wrong. And stupid.
Just because some humans have no respect for life does not mean that governments have to stoop to their level.
