In an introduction to "Daddy" prepared for the BBC, Sylvia Plath explained that
"the poem is spoken by a girl with an Electra complex. Her father died while she thought he was God. Her case is complicated by the fact that her father was also a Nazi and her mother very possibly part Jewish. In the daughter the two strains marry and paralyze each other--she has to act out the awful little allegory once over before she is free of it."
The figure of "Electra" used by Plath is a Greek daughter whose relationship to her tyrannical father--Agamemnon, who sacrificed his other daughter, Iphigenia, to the winds--is erotically charged. After Agamemnon is killed, Electra's mother, Clytemnestra, and her lover, Aegisthus, abuse Electra because of her loyalty to the memory of her father. Out of her hatred toward her mother and her love for her father, Electra urges her exiled brother to return and to kill Clytemnestra and Aegisthus.
The conflation of Agamemnon-father-Hitler-husband is both haunting and powerful in "Daddy," in which the pull of patriarchy is so strong that the daughter/speaker needs to kill her father/husband in order to free herself from them. However, even when she has resolved to kill her father, she is still half in love with him. Give me some lines or imageries that for you illustrate this emotional ambivalence.
