 Collective responsibility refers to the responsibility of a collective entity, e.g., a corporation, a nation state, or a club, for harm in the world. Shared responsibility refers to the responsibility of group members for such harm in cases where they acted together to bring the harm about. Collective responsibility is associated with a single, unified, moral agent. Shared responsibility is associated with individual moral agents who contribute to harm as members of a group either directly through their own actions or indirectly through their membership in the group.
