Just desserts

Jack, Jon and Sam Green remember their father Boris as a decent, mild-mannered man.

But Boris had a painful youth. He was a HolocaustThe murder of six million Jewish people in Europe by Nazi Germany. Members of other minority groups were also killed. survivor.

The Nazis controlled Germany from the early 1930s until the end of World War II.. In 1949, he moved to Australia.

That could have been the end of the story. But a new documentary suggests it was just the end of act one. Revenge: Our Dad the Nazi Killer, released ahead of Holocaust Memorial Day on Saturday, follows the Green brothers as they investigate their own father.

After the war, Australia became a haven for former Nazis fleeing arrest. Revenge sees the Green brothers discover that their father was part of a network of Jews that sought to punish Nazis that had fled down under. He might even have killed some himself.

Revenge has deep roots in our history. The Code of Hammurabi, the oldest recorded set of laws, contains the principle "eye for an eye".² Many stories encourage us to cheer along as a hero gets revenge, from The Count of Monte Cristo to Gladiator.

Revenge can be dangerous. It differs hugely from justice. Justice is an ideal. It is about treating others fairly and with compassion. Revenge, however, is emotional. It comes from negative feelings like anger and hatred.

It often leads to further wrong actions.

Yet there might be some situations where revenge is warrantedJustified or called for. . Journalist Jonathan Freedland writes: "The dirty little secret of the Holocaust... is that no one was punished for it." The Nazi leadership was executed. But countless others escaped punishment. In the face of an unspeakable crime, can revenge be justified when justice fails?

Is revenge always wrong?

Yes: Two wrongs don't make a right. But one wrong often leads to another, then another, then another. Revenge drags everyone into the mud. We should turn the other cheek and trust in justice.

No: Fear is one of the things that makes us human. And fear of revenge keeps society in line. The prospect of facing revenge for a crime might stop us committing that crime in the first place.

Or... Revenge itself is neither right nor wrong. It is born out of our emotions. Most people will want revenge at one point or another. The wrong comes when we hurt others by acting on this desire.
