We must sacrifice something in order to make the world better.

When I joined the UN War Crimes Tribunal, it was a realization of the dream of justice, that finally after Nuremberg, the UN is going to put the accused on trial again! And I still believe that accountability that eradicates impunity is very, very important for transforming the sordid culture of politics and power that we see in the world. But we need to be humble about the fact that justice will not bring back the dead.

Wounds simply won't heal if they are swept under the carpet.

In many instances violence - which obviously inflicts tremendous trauma on victims - also inflicts trauma on the perpetrator. Radical evil takes a lot of preparation, not just from an organizational point of view, but from brainwashing, psychological preparation and the legitimization of violence.

We need to sacrifice something. And this is what I find lacking. We want to construct an image of ourselves as virtuous but we don't want to suffer for our beliefs. We want to change the world with a Facebook like. That's not how the world works.

When we deconstruct how radical evil occurs we realize that it is anything but spontaneous combustion. You need pyromaniacs.

Criminal trials are fundamentally about individual accountability whereas truth commissions are less about the guilt of the perpetrator and more about the suffering of the victim. A criminal trial is only incidentally a therapeutic or cathartic process for victims. But truth commissions, as we saw in South Africa, have the advantage of giving tens of thousands of people the opportunity to tell their stories, and not only does that contribute to healing but it also contributes to reconciliation, especially when perpetrators also come and express contrition.
