Someone asked a tough question in a philosophy group, so I gave
  it my best shot. Tell me how I did, and what your opinion is, if
  you wish.: "can someone justify to me why repeat murders,
  rapists and child rapists shoud be allowed to live in this
  "civilized "society we live in today?" My answer:
  It's because we generally believe that humans are basically
  rational beings that make mistakes and get reason their way
  through their problems. Years of punishment are set for various
  crimes. When you have been kept away for a certain of time, a
  reasonable person will see the error of their ways and
  discontinue the behavior. But ultimately, it is because we treat
  each case as unique for fairness in justice. All things that are
  considered crimes are generally distasteful, some more than
  others and some extremely so. Having a jury allows for reason
  and emotions to mix, with the two lawyers as the "devil" and the
  "angel" being the voices of reason and emotion, the devil's
  emotional reasoning and the angels emotional reasoning. They act
  as your conscience's warring sides. A multiple of jurors are
  mostly hidden unconscious, murmuring through things secretly and
  coming up with a verdict (a reasoned answer, allowing for
  emotional input) The executive brain (the judge) makes the final
  decision. That is my interpretation of a jury trial. I don't
  know if it's true or not. I suspect either the jury system was
  modeled after the human brain or, more likely, the model we have
  of the brain was unconsciously formed by modeling it after the
  jury system. I don't know which came first. They are not special
  cases. Those crimes have set appropriate punishments, changeable
  of course. The danger of treating them differently is precedent.
  If a special case is made for these crimes, special cases will
  then be true for other crimes as well and trickle down to being
  applicable to traffic violations and such. I don't know if I
  agree or disagree, but that's how I see the current way things
  are done in Western countries and justice.
