The Lord said to Cain: “What have you done? The voice of your brother’s blood is crying to me from the ground” (Gen 4:10).The voice of the blood shed by men continues to cry out, from generation to generation, in ever new and different ways.
The Lord’s question: “What have you done?”, which Cain cannot escape, is addressed also to the people of today, to make them realize the extent and gravity of the attacks against life which continue to mark human history; to make them discover what causes these attacks and feeds them; and to make them ponder seriously the consequences which derive from these attacks for the existence of individuals and peoples.
Some threats come from nature itself, but they are made worse by the culpable indifference and negligence of those who could in some cases remedy them. Others are the result of situations of violence, hatred and conflicting interests, which lead people to attack others through murder, war, slaughter and genocide.
And how can we fail to consider the violence against life done to millions of human beings, especially children, who are forced into poverty, malnutrition and hunger because of an unjust distribution of resources between peoples and between social classes? And what of the violence inherent not only in wars as such but in the scandalous arms trade, which spawns the many armed conflicts which stain our world with blood? What of the spreading of death caused by reckless tampering with the world’s ecological balance, by the criminal spread of drugs, or by the promotion of certain kinds of sexual activity which, besides being morally unacceptable, also involve grave risks to life? It is impossible to catalogue completely the vast array of threats to human life, so many are the forms, whether explicit or hidden, in which they appear today! — from Evangelium Vitae (1995)
