Lolita as a form of Exile

The novel Lolita by Vladimir Nabokov can be seen from two different perspectives one as a man who has been deeply hurt due to a frustrated love and therefore, has gone mad and committed a great number of immoral and unethical acts; or two, as a man who has deeply fallen in love with a GIRL and cannot see beyond that point, and cannot measure the degree of his acts, and ultimately learns his lesson and receives what he deserves, or better yet what he has generated from the beginning. However, in both perspectives Lolita seems to be Humbert's way of exile from a painful world in which he cannot seem to fit in, either because of his terrible and frustrated love for Annabel, or the constant appearance or encountering with "nymphets" that are provoking him.
What is most outstanding of the novel though is that at the beginning Humbert seems completely mad and just out of all his senses, but as the novel progresses he seems to reach closer to serenity and understanding. When he starts making his case and defense, he can only talk about the nymphets, but at the end he seems to realize that his behavior is damaging, and Lolita's ultimate fate is only the result of his misdoings to her, and that perhaps she deserves to be away from him.
