Who seems to be more in control of the events in Virgil's The Aeneid the gods and goddesses or the human characters?

In the first few dozen lines of the Aeneid Vergil reminds us that Fate has decreed that Aeneas will travel to Italy and found a city which will eventually give rise to Rome.

progeniem sed enim troiano a sanguine duci

audierat, tyrias olim quae verteret arces;

hinc populum late regem belloque superbum

venturum excidio libyae: sic volvere parcas.

(but she had heard that a race was rising from Trojan blood which would one day topple Carthage' citadel; that from this race would arise a boundless kingdom, proud warriors who would one day undo Africa - that was how destiny worked).

Juno doesn't like this idea, nor does Aeneas (not when he is with Dido). But you have to accept your destiny - that is the message of this poem.
