Frankenstein: death

Mary Shelley, even at the young age when she wrote this novel, shows a firm grasp in Frankenstein on the concept of death.  At the news of William's death, Henry tries to console Victor in saying, "He can no longer be a subject for pity; we must reserve that for his miserable survivors" (Shelley, 48).  This line struck me, because it is something that I have always thought.  Once someone had died, our worry or pity for them is useless.  If they have made it into heaven, they have nothing to worry about or any reason for us to pity them.  When we lose a loved one, we mourn not for them, but for ourselves.  We grieve because they have left us, because we must go on living without their presence.  Henry insists that Victor should not feel bad for William, but should focus his attentions on comforting the members of his family who were still living.  It seems to me that Shelley had strong faith and beliefs based on the last words of Justine.  She focused on the fact that God would carry her through her hardships, and that she would soon be reunited with William.  She often mentions prayers, guardian angels, and destiny as well, all religious references.
