Nature in Frankenstein

Nature, in Frankenstein attributes a lot to Victor's happiness. On page 39, Victor says:
"I remember the first time I became capable of observing outward objects with any kind of pleasure, I perceived that the fallen leaves had disappeared and that the young buds were shooting forth from the trees that shaded my window. It was a divine spring; and the season contributed greatly to my convalescence. I also felt sentiments of joy and affection revive in my bosom; my gloom disappeared, and in a short time I became as cheerful as before I was attacked by the fatal passion.
Up until this point, Victor was dwelling on the fact that he created the "Monster", and was depressed over it. Upon seeing the beauty of nature, it brightened Victor's mood, and for the first time in awhile, he showed some sense of joy. Throughout the book, Victor finds happiness in his surroundings, when William died, it was storming, and Victor found the lightning to be beautiful, and once again, he was somewhat at rest.
