Of course, he just needs a little Liebe =) He's the way he is because he's been shunned from birth..He's known no Liebe only fear, hatred and scorn. I think he definitely needs a hug :) [at least in the 2004 version...my herz broke for him]
Oh...yes. Even when I personally am a Fan of Raoul, in the movie I can really understand him and what his life has been like. As for the book, I'm not so sure, but definitely in the movie.
Well if your a girl there's really nothing to worry about Erik don't have a history of violence towards women... considering is past with his mama. So yeah I'd give him a squeeze, but I would keep my hand at the level of my eyes!
