Well, it is true that you need to become a Werewolf but you never really have to use it. And if you don't use it, you aren't attacked. After you are done with the Companions then you will be given an option to cure yourself as well as the other members of the Companions. Once you are done with that then you never have to even touch on becoming a Werewolf ever again.
