The problem with retributive justice is as I posted before, two wrongs don't make a right. Taking "an eye for an eye" just results in two mutilated people instead of one. Its only purpose is cathartic, and that is retributive justice's other major flaw: it appeals to the worst side of human nature, our sadistic capacity for taking satisfaction in another's suffering. Hence it becomes questionable whether the punishers are really morally superior to the perpetrator.
Opposition to retributive justice has often been expressed, and reform of retributive laws has been growing in Western civilisation since the Enlightenment, also spreading to other cultures. Death penalties are still used in many countries, but public executions are now a thing of the past in all but the most extreme regimes. However, the retributive principle is still very popular, as expressed in public anger and demands for punishment whenever severe crimes are reported in the press. Prison sentences can also be regarded as at least partly retributive, on the understanding that incarceration is what wrongdoers deserve.
Those in Germany who perpetrated these hedinous crimes deserve severe punishment even to death beyond a shadow of a doubt BUT there is simply NO way to justify going into an ethnic German region, rounding up anyone who spoke German, lining them up against a wall and shooting them.
As Chris posted above do we root out the drunk's entire family? And how about all those who saw the drunk and did nothing and those who served the alcohol, and those who saw the accident and did not stop to help and.....
"When you're asked to stay out of a bar you don't just punch the owner--you come back with your army and tear the place down, destroy the whole edifice and everything it stands for. No compromise. If a man gets wise, mash his face. If a woman snubs you, rape her. This is the thinking, if not the reality, behind the whole Hell's Angels act."
