This paper deals with the question of human aggression as a result of evolution and socialization. Two theories by Jonthan Haidt – how socialization and culture affects aggression and how political commitment affects aggression – will be the cornerstone of this work. In the initial part of the paper we have presented definitions of aggression by several well known psychoanalysts, philosophers and ethologists. Their definitions gave us an insight into what aggression really is, why it comes up and in what situations it appears. Understanding the aggression and defining it from different aspects is important because human behaviour or aggression can be delivered in many diffeent ways. It will give us more comprehension on why did Hungary close its borders and showed aggressive behaviors to immigrants that we have listened about in media. Furthermore we have defined evolutionary and sociological aspects of aggresive behaviors. Having in mind that human is a biological prior to social being, we need to understand what triggers it for aggressive behavior and how it manifests. What is there in our genes and how our ancestors affected today's version of human kind? On the other hand, the sociological aspect of aggression is presented and we are explaining why are some behaviors culturally and sociologically determined. Also, how can living in modern communities and national identity affect the mass behavior of a nation. Finally, we are giving a comprehensive insight into the European migration crisis with a focus on Hungary. We are explainingt he policy of Viktor Orban and his government and how it has influenced the Hungarian nation. There are numerous consequences in the form of aggressive behaviors due to manipulation of information and systematic demoralization of immigrants. We are also giving some concrete examples of aggresion during the crisis. In the debate part we are reviewing the migration crisis and how every form of aggressive behavior is associated with the above mentioned definitions of aggression and Haidt's theories. The paper is being concluded with several own theses and final results based on the previously written.
