I understand your point, Naker, but comparing living beings to t-shirts is an unfair analogy. However, using your analogy (where the manager is the goverment, the factory society and the machine the prison system) you are, in effect, suggesting the prison system is at fault. I would disagree with that given that societal views and expectations and the laws we have in place have a greater impact on producing poor t-shirts ;-) Perhaps the analogy you have used isn't quite accurate but I see your point. However, I will say this: your analogy reinforces my previous point regarding the need for science to catchup in order for our laws to be more effective. The "best T-shirt making machine available" if we viewed this machine as the legal system, would be more accurate. Removing that 'reasonable doubt' through science would allow for corporal punishment to exist and function as it should.
As for the 7 yr old girl example, I would reluctantly accept the responsibility for future cancer-caused deaths as I would not sacrifice a single living spirit. Yes it's an emotional repsonse but we are emotional.
In the end, my friend, we will simply have to agree to disagree. :-)
