This article discusses the core question of the legal interests offended by international crimes, and therefore the question of the justification of a rational and moral acceptance of an international criminal jurisdiction. International crimes may start off as violations of human rights, but end up affecting humanity as a whole, not as a supranational statehood or as an institutionalised order or mechanism of international policy-making, but more as a societal relationship and co-existence, an empirical quest into the reality of the meaning of life. They offend the collective art of living in its essential core, i.e., the cultural and ethical diversity as a free creation and promotion of a different meaning of life. The criminalised act is here directed against the collective self-realisation of humanity formed through free intra- and inter-group ethical dialogue, through cultural interaction. This multiculturalism, as a social fact, is expressed in a collective and social-political way and is also affected the same way.
