I do not wish to be melodramatic, but at some point I have to say it. If something bad should happen to me, I want you to know that my commitment to what I am doing has been freely contracted, with the joy of knowing that this is precisely what I should be doing at this moment. Fear is constantly present in each one of us, because none of us are movie heroes. But we refuse to accept that fear must condition our actions and prevent us from doing what with a cool head and fervent heart we understand should be done.

From the last letter received by his family on September 1974
