Fit retribution! Gaul may champ the bit

And foam in fetters; -- but is Earth more free?

Did nations combat to make One submit;

Or league to teach all kings true sovereignty?

In the middle part of the poem, Byron's nobility was shown as he gives respect and credit to people who did honorable deeds, saying that But these are deeds which should not ass away,

And names that must not wither, though the earth

Forgets her empires with a just decay,

The enslavers and the enslaved, their death and birth;

Moreoever, despite of all the loneliness and pain that the narrator had experienced, from his youth up to his old age, as well as those that he witnessed in others' lives, he demonstrated in the near end...

The following indicates this.
Where, for some sin, to Sorrow I was cast,

To act and suffer, but remount at last

With a fresh pinion; which I feel to spring,

Though young, yet waxing vigorous, as the blast

Which it would cope with, on delighted wing,

Spurning the clay-cold bonds with round our being cling.

Moreover, our hero in the poem have shown a figure of a loving father who always thinks of his daughter as he leaves to face the next journey of his life.
