A presente tese propõe um modelo de injusto penal rigorosamente dualista, assimentendido aquele que, ao lado do desvalor da ação, exija sempre e necessariamente a efetivaocorrência de um desvalor do resultado, consistente na afetação, danosa ou perigosa, da esferade existência de terceiros. A hipótese que conduz a investigação é a de que, mesmo diante dosmovimentos expansionistas do poder punitivo hoje verificados, é possível defender a viabilidade de tal concepção de injusto penal. Para a demonstração dessa hipótese, parte-se domodelo dual de sociedade proposto por Jürgen Habermas, que tem na teoria do agircomunicativo a chave para a proteção do mundo da vida frente aos influxos colonizatóriosprovenientes dos sistemas econômico e político administrativo. A partir desse marco teórico,propõe-se uma releitura de alguns dos conceitos fundamentais da teoria do delito, de modo aconferir-lhes interpretação compatível com a concepção dualista rigorosa de injusto adotada.Por fim, para verificar a plausibilidade da hipótese colocada, tais conceitos fundamentais sãopostos à prova diante de situações teóricas tradicionalmente classificadas como de difícilconciliação com uma concepção de injusto baseada na necessária ocorrência de desvalor doresultado, como é o caso dos crimes de perigo abstrato e dos crimes tentados. / The thesis you have in hands proposes a concept of crime in which wrongdoing and harmfulness must be always combined and considered together as elements of a criminal offense in order to demonstrate the real affectation of third parties. The main hypothesis is that even facing an expansionist tendency toward incarceration and overcriminalization it is still possible to defend the viability of such a concept of crime. With the purpose of demonstrate this hypothesis, the Habermas's dualistic society model and his theory of communicative action are taken as a point of departure and based on them we intend to review some of the elements that compose the concept of criminal offense. Finally, the thesis will be challenged against controversial existing rulings (such as victimless crimes) to verify if their reasoning are compatible with such a dualistic concept of crime, which deny the possibility of existing criminal offenses without harm to others.

An accused cannot be held criminally liable by a court until he is considered to be culpable, a process which entails establishing criminal capacity and intention (dolus) or negligence (culpa). Determining a perpetrator’s necessary intent in the form of dolus eventualis has proved to be a predicament in South African jurisprudence. This type of intent occurs when a person does not aim to cause the unlawful act, however, he subjectively foresees the likelihood that in pursuing with his conduct, the unlawful result will possibly happen, and he reconciles himself to this possibility. The problem with this form of intention, especially where the death of another is caused recklessly, is, amongst others, reservations as to whether the perpetrator’s foresight was of a real, reasonable or a remote possibility. This research examines the imperatives and rationale for preceding and current interpretations and applications of dolus eventualis and associate concepts in South African as well as in selected foreign legal frameworks in order to provide a comprehensive perspective on the subject. In this regard, the study challenges conflicting judgments on the application of dolus eventualis in domestic courts, especially as regards homicide- and putative private defence cases, amongst others. It is evidenced that in case law concerning dolus eventualis, legal rules were not properly articulated when determining this type of criminal intent. In this investigation, the legislative framework applicable to dolus eventualis under international law is also critically evaluated with the aim of facilitating the comprehension of this element in South African law. As the concept of dolus eventualis is an indispensable concept in South African criminal law, recommendations are proposed on the application and interpretation of dolus eventualis suitable to the South African landscape, which includes possible law reform. / Criminal and Procedural Law / LL.
