How does the following statement apply to victors tortured condition? "The wounded deer dragging its fainting limbs to some untrodden brake, there to gaze upon the arrow which had peirced it, and to die, was but a type of me."

The deer pretty much represents how Victor feels at this point in the novel. Victor feels emotionally wounded to the point he cannot go on. He is physically exhausted and finds the deer's plight an apt metaphor for his own demise. The creature has already shot his "arrow" at Victor and he (Victor) slowly bleeds his soul and spirit away.
