Final answer:
In the ancient Greek epic, The Iliad, Achilles is characterized as being controlled by his anger more than Hektor. His wrath plays a significant role in defining his character, and is directed at both enemies and allies.
Step-by-step explanation:
The character who is most often controlled by his anger in the literature in question is Achilles. In the ancient Greek epic, The Iliad by Homer, Achilles is one of the central characters and is often identified by his anger, which plays a significant role in establishing his character identity. His wrath is not only directed at his enemies in battle, but also towards his own allies, notably Agamemnon, which is even the central conflict in the beginning of the epic. On the contrast, Hector, another central character in the epic, is shown to be more rational and controlled. Therefore, amongst the two choices provided, Achilles can be characterized as being controlled by his anger.
