Literary analysis of the theme nature versus nurture in the novel Frankenstein.

The Creature in Shelley's
Frankenstein is not nurtured and, thus, becomes a
Monster. 

Victor rejects his creation immediately due to
the Creature's appearance.  His rejection is due to the superficial.  The creature, left
alone to progress on his own, becomes hideous.  This is what becomes of natural
man. 

Contrast this, for instance, with Elizabeth.  She,
too, is orphaned (as the Creature is, for all practical purposes), but she is accepted
and loved and taken care of.  And she becomes an almost ideal
person. 

Victor bears responsibility for the Creature
becoming a Monster, because he fails to nurture his creation.
