The rapid transformation of the modern world has a profound impact on the lives, attitudes and religiousness of youth. The spontaneous influx of refugees throughout Europe from Muslim countries raises fears of a further intensification in the wave of terrorist attacks and increased violence founded in Islamic ideology. In Germany, there is particular anxiety resulting from manifestations of Islamic fanaticism. An extreme case of this is the terrorist version of jihad occurring among Muslim youth. German scientists perceive the reasons for this phenomenon lie in the almost total failure of the policy of multiculturalism. The problem lies in the fact that - in light of empirical research - 25% of Muslims living in Germany reject all integration projects. This increases the gap between Muslims and the rest of society and the danger of further radicalisation, especially of Muslim youth. Confirmation of this can be shown through a comparative analysis of generation John Paul II (JP2) and generation jihad because it shows the significant differences, among which the most expressive are the attitudes, behaviours and actions of the participants, of the social phenomena compared. Following the death of the Polish Pope, participants of generation JP2 regret that they did not listen to his teachings and did not pursue the values he proclaimed. After the death of Pope John Paul II many people declared a revision of their own lives, although the results of scientific research do not confirm that they have become better Catholics and citizens. On the other hand, generation jihad - following absolutely the lifestyle defined by Islam - does not declare any changes in religious attitudes and thus does not seek to assimilate with the German community. In the end all this leads to acts of aggression, violence and sadistic practice by participants of generation jihad. On the basis of the terrorist attacks carried out in the years 2001-2016 it can be assumed that jihadism is a cult of death, of which the so-called Islamic State is a vivid, and at the same time tragic, example.
