This paper provides a formalization of the other-condemning anger emotion which is a social type of anger triggered by the behaviour of other agents. Other-condemning anger responds to frustration of committed goals by others, and motivates goal-congruent behavior towards the blameworthy agents. Understanding this type of anger is crucial for modelling human behavior in social settings as well as designing socially aware artificial systems. We utilize existing psychological theories on other-condemning anger and propose a logical framework to formally specify this emotion. The logical framework is based on dynamic multi-agent logic with graded cognitive attitudes.
