This study investigated the role of moral indignation emerging in the wake of the 6 February earthquakes, the structural failures diagnosed by this emotion, and the conditions under which it translates into social action. Drawing on in-depth interviews with fifteen individuals engaged in volunteering and activism in Hatay, Turkey, the research revealed that indignation served as a diagnostic force rooted in the violation of the sanctity of life, justice, and equality. However, the findings suggested that indignation alone was insufficient; for it to be transformed into sustainable collective action, a dynamic synergy with hope was required. The analysis deciphered how indignation rendered systemic failures and historical traumas visible, while hope purged this emotion of resentment or melancholy, transforming it into a form of professional agency. The primary originality of this research lies in its transition from a perspective initially focused on anger to a synthesis of “hopeful indignation”—a concept that bridged critical reflexivity with constructive energy. By positioning emotions as catalysts for political resistance rather than pathological reactions, this study proposed a radical intervention framework for social work. It advocated for a professional shift from merely alleviating anger toward organizing it through the transformative power of hope.
