Part I of this paper discussed various dynamic aspects of hate in the individual developmental and clinical context. Part II, also an expansion of the author’s discussion of Harold Blum’s presentation on “Hate and its vicissitudes” in Prague in 2017, examines the theme of hate as a multidimensional dynamic group phenomenon. The paper uses various theoretical perspectives to focus on group unconscious processes and the group-specific dynamic of regression leading to an activation of primitive ego operations, unleashing destructive aggression as well as creative mobilization. Also considered are the implications in terms of destruction, adaptation, and creativity, in relation to group unconscious dynamic processes and intergenerationally trasmitted trauma and posttraumatic developments.
