why does shelley end ch 12 on an apparently optomistic note

Nonetheless, he dreams of winning the love of the cottagers by mastering their language; in this way can he reveal to them the beauty and gentleness of his soul. I suppose there is a little hope in this but somehow the reader has lost more faith in humanity than even the creature has.
