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!
11. Here though we shall concentrate particular attention on another category of attacks, affecting life in its earliest and in its final stages, attacks which present new characteristics with respect to the past and which raise questions of extraordinary seriousness. It is not only that in generalized opinion these attacks tend no longer to be considered as "crimes"; paradoxically they assume the nature of "rights", to the point that the State is called upon to give them legal recognition and to make them available through the free services of health-care personnel. Such attacks strike human life at the time of its greatest frailty, when it lacks any means of self-defence. Even more serious is the fact that, most often, those attacks are carried out in the very heart of and with the complicity of the family-the family which by its nature is called to be the "sanctuary of life".
How did such a situation come about? Many different factors have to be taken into account. In the background there is the profound crisis of culture, which generates scepticism in relation to the very foundations of knowledge and ethics, and which makes it increasingly difficult to grasp clearly the meaning of what man is, the meaning of his rights and his duties. Then there are all kinds of existential and interpersonal difficulties, made worse by the complexity of a society in which individuals, couples and families are often left alone with their problems. There are situations of acute poverty, anxiety or frustration in which the struggle to make ends meet, the presence of unbearable pain, or instances of violence, especially against women, make the choice to defend and promote life so demanding as sometimes to reach the point of heroism.
All this explains, at least in part, how the value of life can today undergo a kind of "eclipse", even though conscience does not cease to point to it as a sacred and inviolable value, as is evident in the tendency to disguise certain crimes against life in its early or final stages by using innocuous medical terms which distract attention from the fact that what is involved is the right to life of an actual human person.
12. In fact, while the climate of widespread moral uncertainty can in some way be explained by the multiplicity and gravity of today's social problems, and these can sometimes mitigate the subjective responsibility of individuals, it is no less true that we are confronted by an even larger reality, which can be described as a veritable structure of sin. This reality is characterized by the emergence of a culture which denies solidarity and in many cases takes the form of a veritable "culture of death". This culture is actively fostered by powerful cultural, economic and political currents which encourage an idea of society excessively concerned with efficiency. Looking at the situation from this point of view, it is possible to speak in a certain sense of a war of the powerful against the weak: a life which would require greater acceptance, love and care is considered useless, or held to be an intolerable burden, and is therefore rejected in one way or another. A person who, because of illness, handicap or, more simply, just by existing, compromises the well-being or life-style of those who are more favoured tends to be looked upon as an enemy to be resisted or eliminated. In this way a kind of "conspiracy against life" is unleashed. This conspiracy involves not only individuals in their personal, family or group relationships, but goes far beyond, to the point of damaging and distorting, at the international level, relations between peoples and States.
13. In order to facilitate the spread of abortion, enormous sums of money have been invested and continue to be invested in the production of pharmaceutical products which make it possible to kill the fetus in the mother's womb without recourse to medical assistance. On this point, scientific research itself seems to be almost exclusively preoccupied with developing products which are ever more simple and effective in suppressing life and which at the same time are capable of removing abortion from any kind of control or social responsibility.
It is frequently asserted that contraception, if made safe and available to all, is the most effective remedy against abortion. The Catholic Church is then accused of actually promoting abortion, because she obstinately continues to teach the moral unlawfulness of contraception. When looked at carefully, this objection is clearly unfounded. It may be that many people use contraception with a view to excluding the subsequent temptation of abortion. But the negative values inherent in the "contraceptive mentality"-which is very different from responsible parenthood, lived in respect for the full truth of the conjugal act-are such that they in fact strengthen this temptation when an unwanted life is conceived. Indeed, the pro- abortion culture is especially strong precisely where the Church's teaching on contraception is rejected. Certainly, from the moral point of view contraception and abortion arespecifically different evils: the former contradicts the full truth of the sexual act as the proper expression of conjugal love, while the latter destroys the life of a human being; the former is opposed to the virtue of chastity in marriage, the latter is opposed to the virtue of justice and directly violates the divine commandment "You shall not kill".
But despite their differences of nature and moral gravity, contraception and abortion are often closely connected, as fruits of the same tree. It is true that in many cases contraception and even abortion are practised under the pressure of real- life difficulties, which nonetheless can never exonerate from striving to observe God's law fully. Still, in very many other instances such practices are rooted in a hedonistic mentality unwilling to accept responsibility in matters of sexuality, and they imply a self-centered concept of freedom, which regards procreation as an obstacle to personal fulfilment. The life which could result from a sexual encounter thus becomes an enemy to be avoided at all costs, and abortion becomes the only possible decisive response to failed contraception.
The close connection which exists, in mentality, between the practice of contraception and that of abortion is becoming increasingly obvious. It is being demonstrated in an alarming way by the development of chemical products, intrauterine devices and vaccines which, distributed with the same ease as contraceptives, really act as abortifacients in the very early stages of the development of the life of the new human being.
14. The various techniques of artificial reproduction, which would seem to be at the service of life and which are frequently used with this intention, actually open the door to new threats against life. Apart from the fact that they are morally unacceptable, since they separate procreation from the fully human context of the conjugal act, 14 these techniques have a high rate of failure: not just failure in relation to fertilization but with regard to the subsequent development of the embryo, which is exposed to the risk of death, generally within a very short space of time. Furthermore, the number of embryos produced is often greater than that needed for implantation in the woman's womb, and these so-called "spare embryos" are then destroyed or used for research which, under the pretext of scientific or medical progress, in fact reduces human life to the level of simple "biological material" to be freely disposed of.
Prenatal diagnosis, which presents no moral objections if carried out in order to identify the medical treatment which may be needed by the child in the womb, all too often becomes an opportunity for proposing and procuring an abortion. This is eugenic abortion, justified in public opinion on the basis of a mentality-mistakenly held to be consistent with the demands of "therapeutic interventions"-which accepts life only under certain conditions and rejects it when it is affected by any limitation, handicap or illness.
Following this same logic, the point has been reached where the most basic care, even nourishment, is denied to babies born with serious handicaps or illnesses. The contemporary scene, moreover, is becoming even more alarming by reason of the proposals, advanced here and there, to justify even infanticide, following the same arguments used to justify the right to abortion. In this way, we revert to a state of barbarism which one hoped had been left behind forever.
15. Threats which are no less serious hang over the incurably ill and the dying. In a social and cultural context which makes it more difficult to face and accept suffering, the temptation becomes all the greater to resolve the problem of suffering by eliminating it at the root, by hastening death so that it occurs at the moment considered most suitable.
Various considerations usually contribute to such a decision, all of which converge in the same terrible outcome. In the sick person the sense of anguish, of severe discomfort, and even of desperation brought on by intense and prolonged suffering can be a decisive factor. Such a situation can threaten the already fragile equilibrium of an individual's personal and family life, with the result that, on the one hand, the sick person, despite the help of increasingly effective medical and social assistance, risks feeling overwhelmed by his or her own frailty; and on the other hand, those close to the sick person can be moved by an understandable even if misplaced compassion. All this is aggravated by a cultural climate which fails to perceive any meaning or value in suffering, but rather considers suffering the epitome of evil, to be eliminated at all costs. This is especially the case in the absence of a religious outlook which could help to provide a positive understanding of the mystery of suffering.
On a more general level, there exists in contemporary culture a certain Promethean attitude which leads people to think that they can control life and death by taking the decisions about them into their own hands. What really happens in this case is that the individual is overcome and crushed by a death deprived of any prospect of meaning or hope. We see a tragic expression of all this in the spread of euthanasia-disguised and surreptitious, or practised openly and even legally. As well as for reasons of a misguided pity at the sight of the patient's suffering, euthanasia is sometimes justified by the utilitarian motive of avoiding costs which bring no return and which weigh heavily on society. Thus it is proposed to eliminate malformed babies, the severely handicapped, the disabled, the elderly, especially when they are not self-sufficient, and the terminally ill. Nor can we remain silent in the face of other more furtive, but no less serious and real, forms of euthanasia. These could occur for example when, in order to increase the availability of organs for transplants, organs are removed without respecting objective and adequate criteria which verify the death of the donor.
16. Another present-day phenomenon, frequently used to justify threats and attacks against life, is the demographic question. This question arises in different ways in different parts of the world. In the rich and developed countries there is a disturbing decline or collapse of the birthrate. The poorer countries, on the other hand, generally have a high rate of population growth, difficult to sustain in the context of low economic and social development, and especially where there is extreme underdevelopment. In the face of over- population in the poorer countries, instead of forms of global intervention at the international level-serious family and social policies, programmes of cultural development and of fair production and distribution of resources-anti-birth policies continue to be enacted.
Contraception, sterilization and abortion are certainly part of the reason why in some cases there is a sharp decline in the birthrate. It is not difficult to be tempted to use the same methods and attacks against life also where there is a situation of "demographic explosion".
The Pharaoh of old, haunted by the presence and increase of the children of Israel, submitted them to every kind of oppression and ordered that every male child born of the Hebrew women was to be killed (cf. Ex 1:7-22). Today not a few of the powerful of the earth act in the same way. They too are haunted by the current demographic growth, and fear that the most prolific and poorest peoples represent a threat for the well-being and peace of their own countries. Consequently, rather than wishing to face and solve these serious problems with respect for the dignity of individuals and families and for every person's inviolable right to life, they prefer to promote and impose by whatever means a massive programme of birth control. Even the economic help which they would be ready to give is unjustly made conditional on the acceptance of an anti-birth policy.
17. Humanity today offers us a truly alarming spectacle, if we consider not only how extensively attacks on life are spreading but also their unheard-of numerical proportion, and the fact that they receive widespread and powerful support from a broad consensus on the part of society, from widespread legal approval and the involvement of certain sectors of health-care personnel.
As I emphatically stated at Denver, on the occasion of the Eighth World Youth Day, "with time the threats against life have not grown weaker. They are taking on vast proportions. They are not only threats coming from the outside, from the forces of nature or the ?Cains' who kill the ?Abels'; no, they are scientifically and systematically programmed threats. The twentieth century will have been an era of massive attacks on life, an endless series of wars and a continual taking of innocent human life. False prophets and false teachers have had the greatest success".15 Aside from intentions, which can be varied and perhaps can seem convincing at times, especially if presented in the name of solidarity, we are in fact faced by an objective "conspiracy against life", involving even international Institutions, engaged in encouraging and carrying out actual campaigns to make contraception, sterilization and abortion widely available. Nor can it be denied that the mass media are often implicated in this conspiracy, by lending credit to that culture which presents recourse to contraception, sterilization, abortion and even euthanasia as a mark of progress and a victory of freedom, while depicting as enemies of freedom and progress those positions which are unreservedly pro-life.
