The modern world is still marked by many manifestations of evil, which is always taking on newer forms. There are, for example, military operations, sanctions, crimes, assassinations and killings. Currently, this dramatic list is complemented by terrorism, which has become a sign of modern civilization. These aspects of civilization improve the tools and methods to fight against life, solidarity, against goodness, justice and peace. Therefore, every manifestation of terrorism causes deep pain, brings suffering, because it painfully hurts the entire human civilization. This barbarism deserves universal condemnation always and in all circumstances. It works against the human person and interpersonal solidarity. It is of an extremist nature, because one of the foundations of its action is the absolutization of political or economic interests, in accordance with the principle "the end justifies the means". Terrorism is a real crime against humanity.
