A Possible Theme?

I have discovered a possible theme!  Throughout Frankenstein by Mary Shelley, the plot seems to portray the consequences of "playing God."  This theme, which many terrible sci-fi movies have explored, condones actions which weren't meant for humans.  Often, this includes mass genocide, bringing the dead to life, or creating new life.  This is the case in Frankenstein.  In the story, Victor possess great scientific curiosity and ability.  These traits, combined with motivation in the form of his mother's death, allow him to create the creature (who I will call Frank for no specific reason).  Obviously, this doesn't turn out well for him, as he thinks it is horrible, he is scarred, and his brother ends up dying.  However, this theme seems to also be reflected in the nature that often appears in the novel.  This is especially evident when Victor is exploring the Alps and surrounding valleys after William's death.

"The sound of the the river raging among the rocks, and their dashing of the waterfalls around, spoke of a power mighty as Omnipotence - and I ceased to fear, or to bend before any being less almighty than that which had created and ruled the elements  here displayed in their most terrific guise (p 64)."

This passage clearly shows thoughts which recognize the power of God or another greater being.  I think they reveal a change in Victor's thinking.  He now realizes that he "played God" and that he went against the rules of nature.  He sees beauty in the nature around him which strongly contrasts with the figure of Frank which he describes as horrifying and dreadful.  He seems to think that "playing God" was never a good idea.
