Objectivity and justice have nothing to do with one another.
It's a good quote, and one that really gets you thinking.
How can anyone hand out punishment and pardon if they have no feeling and emotion concerning the crime they judge?
Can a man who is objective to the murder of another man really feel the need for the killer's sentence? Could they be swayed by a well-placed, sensible argument? Is focusing solely on fact and evidence really the best way to decree justice?
How can you decide who's done who wrong if you can feel no passion for a life lost, a body done wrong, or a right encroached upon?
