Nothing can save you now –
not even your silver whirling, mighty-tiding river –
not for all the bulls you’ve slaughtered to it for years,
the rearing stallions drowned alive in its eddies…die! –
even so – writhing in death till all you Trojans pay
for Patroclus’ blood and the carnage of Achaeans
killed by the racing ships when I was out of action.

– Homer

The Iliad, Book 21, lines 149-155. Achilles kills Priam’s youngest son Lycaon, despite his plea to be spared. Achilles is now a pure killing machine, vowing to dispense death to all Trojans to pay for Patroclus’s blood.
