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.

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

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.

Helping survivors of residential schools in Canada is not the same as the UN sending in peacekeepers to prevent the genocide in Rwanda. But both are a reflection of our culture and of our priorities. Where there is empathy there is always a solution, where there is apathy there is always an excuse.

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.

There are realities that one needs to deal with, but very often what we are told is political reality is merely cynicism. One could equally say that slavery is a reality, and misogyny too.

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