Book 6

“No we must leave not a single
Trojan alive, not even the baby boy
that his mother still holds in her womb-not even one
must slip from our hands now. All the males must be slaughtered,
every last male in Troy, unmourned, unburied.”
(6.57-61)

That expresses things fairly succinctly.

It brings to mind examples in the Old Testament such as I Samuel 15:3  in which Saul is told by the Lord to “kill both man and woman, infant and nursing child, ox and sheep, camel and donkey.”

It’s interesting to note that a little later in Book 6 (6.216-240) Diomedes and Glaucus although on opposite sides are not able to kill each other since their grandfathers were friends.
