Ivan's Legacy

Ivan, a violin maker in his 70’s, had cancer. He takes in Kelly, a pregnant 14-y-o drug addicted street kid. When he goes for chemotherapy Kelly overdoses. Ivan refuses to have further chemotherapy as he doesn’t want to leave Kelly on her own. He dies (otherwise there’d be no legacy, would there?). He leaves Kelly everything he owns (he has considerable assets). Will Kelly come good, or did Ivan sacrifice his life in vain?
