Ok, let's deconstruct this mess.
"Emotionally unbalanced? Quite certain that would render me useless in my job as a trauma nurse" - Dealing with victims isn't the same as dealing with criminals, simply this statement gives you no green card for ignorance on this subject.
"a job which has in turn made me pretty jaded toward the usefulness of the 'dregs of society'" - Another emotive charged meaningless statement, so you are jaded.. - so what?, it gives you no excuse to be ignorant.
"I understand too what is ''required to contemplate the finer points of a retributive justice system'' - evidently not.
"However the 'justice system' fails most people. Take the story today of five murderers given 'life' in prison yet all were released and murdered again, some within weeks of release." - Explain what this has to do with killing people in response to property theft.
I'll hazard a guess at absolutely nothing, also if you could please expand upon "fails most people" - most, that implies above 50%?, do you have any data to back up this daily mail style headline, or is this more emotionally charged hot air?.
If you want to have a discussion on issues regarding risk assessment on the release of people incarcerated for murder then perhaps you should make a thread about that, but don't you see how dropping in completely unrelated
story's gives
you impression you are lacking in the brains department?.
