Then arrives the monster, and they fight for Elizabeth's affections, but Elizabeth, horrified by what she has become, commits suicide by setting herself on fire. In my opinion, although he wanted to create life, and defeat death, the result was contrary. Life is not science or experiments, but love.

   So late into the night, 

Though the heart be still as loving, 

   And the moon be still as bright. 

For the sword outwears its sheath, 

   And the soul wears out the breast, 

And the heart must pause to breathe, 

   And love itself have rest. 

Though the night was made for loving, 

   And the day returns too soon, 

Yet we'll go no more a roving 

   By the light of the moon.

In Wordsworth's poems nature has different role: nature as countriside, as sourche of ispiration and as a life force.
He was born in Lake District an area of supreme natural beauty.

 Not in lone splendour hung aloft the night 

And watching, with eternal lids apart, 

 Like nature's patient, sleepless Eremite, 

The moving waters at their priestlike task 

 Of pure ablution round earth's human shores, 

Or gazing on the new soft-fallen mask
Of snow upon the mountains and the moors— 

No—yet still stedfast, still unchangeable, 

 Pillow'd upon my fair love's ripening breast, 

To feel for ever its soft fall and swell, 

 Awake for ever in a sweet unrest, 

Still, still to hear her tender-taken breath, 

And so live ever—or else swoon to death.
