The aim of the article is to study the Ukrainians’ understanding of social collective and individual responsibility in the context of the Russia-Ukraine military conflict. Research methods and materials. Discourse analysis was selected as the most suitable method. The research material was publications and comments posted on Facebook in the period from 24.02.2022 to 15.05.2022 by Ukrainian social media users. Results and discussion. Although in the Ukrainian sector of social networks responsibility for military aggression is undoubtedly seen as collective, it is unequally shared among groups. During sharing of collective responsibility Ukrainians distinct two approaches: 1) all citizens of the aggressor country are equally to blame; 2) citizens of the aggressor country may be related to the crime on different scales, so they have different levels of responsibility. In the view of Ukrainians, the main responsibility should be ascribed to those who can be called a “random collection of individuals.” After the beginning of the Russia-Ukraine military conflict the concept of personal responsibility has been losing its meaning, and the relationship between an individual, social group and society as a whole is prioritized by collective responsibility. Herewith, it is not the culpable event or action that is emphasized, but the “metaphysical guilt” that is imposed on all citizens of the aggressor country on the basis of membership in a “vicious” community.
