This thesis is an exploration of the concept of evil. It attempts to define what we mean by this elusive concept and its relevance to human behaviour. The thesis then develops an operational definition of evil that is distilled from the writings of various social scientists. The thesis argues, however, that in addition to merely defining evil, there are three emotive elements that also go towards our preparedness to label an act as evil. The thesis then examines the causes of evil acts. The thesis argues that the interactive causation, of situation and disposition, is the most robust explanation of evil acts. The thesis rejects the notion of the evil person, instead arguing that it is ordinary people who commit evil acts. The thesis then examines the causes of genocide, the most evil of acts, and links this back to the previous discussion of causal factors of evil acts. Germany’s war against the Soviet Union in World War II, in particular the role of the Waffen-SS is then discussed. The death and destruction during this conflict would result not just from military operations, but also from the systematic killing and abuse that the Waffen-SS directed against Jews, Communists and ordinary citizens. The thesis then utilises the case study of the Waffen-SS to highlight the application of the interactive causation explanation in regards to evil acts. The conventional wisdom that the Waffen-SS in WWII fought a relatively clean fight, unsullied by the atrocities committed by the Nazis, is challenged—and largely demolished. Focusing on the Eastern Front, the thesis contends that the Nazi vision of a racial-ideological death struggle against Slavic hordes and their Jewish-Bolshevik commissars resonated with soldiers of the Waffen-SS, steeped in traditional anti-Semitic and racist dogmas. In doing so the thesis clearly shows that the Waffen-SS was an organisation that committed widespread atrocities. The thesis then applies the operational definition of evil to the case study and determines that the acts committed by the Waffen-SS were in fact evil. It also contends that the concept of evil is useful in explaining human atrocity. In conducting this examination the thesis provides some insight into the challenges facing society from preventing future broad-scale acts of evil.

Dans ses documents officiels, le Magistère de l’Église catholique qualifie souvent la contraception artificielle intraconjugale d’acte intrinsèquement mauvais. Le recours à cette notion semble considérer la nature biologique comme l’index impératif d’une norme morale sans autre considération. De quoi dépend alors la moralité d’un acte ? Une technique, prise en elle-même, comporte-t-elle une valeur morale définie ? Pour répondre à ces questions, nous avons retracé l’évolution de cette notion à travers une relecture de ses enjeux théologiques en les fondant sur la circulation de plusieurs pôles de réflexion (Écriture, Tradition, raison, sciences, vécu). Pour dissiper les ambiguïtés liées à cette notion, nous avons estimé qu’il serait préférable d’employer l’expression d’acte injustifiable plutôt que celle d’acte intrinsèquement mauvais. La notion d’acte injustifiable a l’avantage de faire droit à l’herméneutique et à l’exercice de la raison pratique dans le discernement éthique. Ainsi, on peut faire droit à la pluralité et articuler au mieux la temporalité et la complexité systémique dans le jugement moral des actes humains / In its official documents, the Magisterium of the Catholic Church often refers to intra-marital artificial contraception as an intrinsically evil act. The use of this concept seems to consider the biological nature as an imperative index of a moral standard without other considerations. If artificial contraception is wrong in itself, then what place do we give to conscience and freedom of couples in birth control? Is there an irreducible opposition between the natural law and contraceptive techniques? Does a technique, if taken by itself, hold a defined moral value? To answer these questions, we have traced back the evolution of this concept through a rereading of its anthropological-theological issues based on the circulation of several poles of thought (Scripture, Tradition and Reason, Humanities, Experience, etc.). To dispel any equivocities and ambiguities related to this concept, we believe it is better to use the term unjustifiable act rather than that of an intrinsically evil act. The concept of unjustifiable act has the advantage of granting hermeneutics and the use of practical reason in ethical discernment. In this way, we can honor otherness (recognition of particularities and subjectivities, while searching for the universal), grant the plurality of actions, norms and systems of legitimation of standards and allow regulation to better enable the regulation of historicity, temporality and systemic complexity in moral judgment of human actions.
