The article is devoted to a comparative analysis of the concepts of “good” and “evil” in Russian and English languages based on paremiology.Proverbs and sayings as a form of folk wisdom reflect key moral values and cultural attitudes of different nations. The work examines the similarities and differences in the interpretation of good and evil in Russian and English, as well as their influence on the worldview of speakers. In Russian, goodness is traditionally associated with self-sacrifice, collectivism, and spiritual values, whereas in the English tradition, it is more often associated with individual responsibility, practical benefit, and social justice. An analysis of proverbs demonstrates that, despite the universality of moral categories, their cultural interpretation varies significantly.
