Has Aphrodite killed anyone

Answer 1

Yes:

The six sons of Halia would not let her come ashore and she caused their madness; Poseidon later buried these sons for their deeds in madness.

Hippolytos, son of Theseus disdained Aphrodite's worship and she is said to have caused his death.

Hippomenes, after defeating Atalanta later forgot to thank Aphrodite and in her wrath she caused them to be changed into lions shortly after.

Helios's lover Leukothea; because Helios had seen her affair with Ares.

Kalliope's son Orpheus (to punish Kalliope in her judgement of Adonis between Aphrodite and Persephone; some say also to punish him for scorning women and only consorting in love with boys).

Heracles incurred Aphrodite's wrath when he seduced her mortal lover Adonis. The goddess retaliated by instructing the dying kentauros Nessos to have Deianeira (the wife of Herakles) soak a robe in his poisoned blood, and present it to Herakles as a love-charm should he ever prove unfaithful. She did so, and the poisoned robe brought about the hero's death.

Glaukos; who tried to prevent his mares from mating and Aphrodite drove them made and they tore him to pieces.

Narcissus, for scorning love.
