Everything can be good or evil.. everything depends on what is already in your heart and on the way you look at things.. even if they are only fantasy matters.. I mean.. if you take this too seriously I don't think it is gonna be sane.. otherwise, if you take narrative as what it really is, that is a work of mere entartaining, amazing fiction, that could be good.. no harm underneath..! Just enjoy it and let your brilliant immaginitive power be enhanced by it..!
