I believe that Agamemnon’s death was equally
- a symptom of the family curse
- a consequence of the king’s actions (prior & after the War)
- Clytaemnestra’s decision (with Aegisthus’ kind encouragement & assistance)
Certain scholars also mention political transitions (e.g., from the custom of blood feud to public courts of law, and/or from a matrilineal to a patrilineal society) as central themes in the Aeschylus’ play.
