Explain the effects of Victor's guilt on his spirit. How else is he affected by his state of mind? In Chapter 9

Victor is tormented by the false calm that descends upon the Frankenstein household following the death of Justine. He is wracked with guilt; though he intended to further the cause of human happiness, he has ended in committing "deeds of mischief beyond description horrible." Victor's health suffers as a result of his massive sense of guilt and the bleak depression that accompanies it. His father, observing his misery, becomes ill as well....Victor passes most of his hours in solitude; the fact that he must keep his role in William's death a secret makes the company of his family agonizing to him.
