At the same time a new cultural climate is developing and taking hold, which gives crimes against life a new and-if possible-even more sinister character, giving rise to further grave concern: broad sectors of public opinion justify certain crimes against life in the name of the rights of individual freedom, and on this basis they claim not only exemption from punishment but even authorization by the State, so that these things can be done with total freedom and indeed with the free assistance of health-care systems. All this is causing a profound change in the way in which life and relationships between people are considered. The fact that legislation in many countries, perhaps even departing from basic principles of their Constitutions, has determined not to punish these practices against life, and even to make them altogether legal, is both a disturbing symptom and a significant cause of grave moral decline. Choices once unanimously considered criminal and rejected by the common moral sense are gradually becoming socially acceptable. Even certain sectors of the medical profession, which by its calling is directed to the defence and care of human life, are increasingly willing to carry out these acts against the person. In this way the very nature of the medical profession is distorted and contradicted, and the dignity of those who practise it is degraded. In such a cultural and legislative situation, the serious demographic, social and family problems which weigh upon many of the world's peoples and which require responsible and effective attention from national and international bodies, are left open to false and deceptive solutions, opposed to the truth and the good of persons and nations.
The end result of this is tragic: not only is the fact of the destruction of so many human lives still to be born or in their final stage extremely grave and disturbing, but no less grave and disturbing is the fact that conscience itself, darkened as it were by such widespread conditioning, is finding it increasingly difficult to distinguish between good and evil in what concerns the basic value of human life. Today there exists a great multitude of weak and defenceless human beings, unborn children in particular, whose fundamental right to life is being trampled upon.
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.
