Does "one only being" refer to "humankind"?
Does "One only being shalt thou not subdue" mean "You shall not subdue humankind?"
Context:
Fiend, I defy thee! with a calm, fixed mind,
All that thou canst inflict I bid thee do;
Foul Tyrant both of Gods and Human-kind,
One only being shalt thou not subdue....
Thou art omnipotent.
O'er all things but thyself I gave thee power,
And my own will....
I curse thee! let a sufferer's curse
Clasp thee, his torturer, like remorse;
'Till thine Infinity shall be
A robe of envenomed agony;
And thine Omnipotence a crown of pain,
To cling like burning gold round thy dissolving brain.[23]
