From the story of Christian de Chergé, who forgave his murderer 2 years before he was killed, in a prophetic letter:
"I would like, when the time comes, to have a space of clearness that would allow me to beg forgiveness of God and of my fellow human beings, and at the same time to forgive with all my heart the one who will strike me down ... In this 'Thank you,' which is said for everything in my life from now on, I certainly include you, my last-minute friend who will not have known what you are doing ... I commend you to the God in whose face I see yours. And may we find each other, happy 'good thieves' in Paradise, if it please God, the Father of us both."
