To marry a man out of pity is folly; and if you think you are going to influence the kind of fellow who has 'never had a chance, poor devil', you are profoundly mistaken. One can only influence the strong characters in life, not the weak; and it is the height of vanity to suppose that you can make an honest man of anyone.
There is no such thing as a good influence. Because to influence a person is to give him one's own soul. He does not think his natural thoughts, or burn with his natural passions. His virtures are not real to him. His sins, if there are such thing as sins, are borrowed. He becomes an echo of someone else's music, an actor of a part that has not been written for him.
