Probably one of the reasons that the Pack hasn't
dealt with Gus is that he's just barely inside the limits that Con set for acceptable behaviour within the Pack.
We need to take our Human filters off: Gus is reprehensible as a Man; but is he that obnoxious as a Wolf? He's an Old-Style
Werewolf, people; and he's raising his daughter the way HE was probably raised.
Gus would probably be so upset by our comparing him to a Human that he would be very injured and hurt...
and tell you so before he tore you limb from limb.
He's also about as sharp as a two-headed tack...
As for Rebecca; she seems to have a more gentle nature, just based on how she dealt with Ms. Hewitt, the fabric store lady. Remember, though-she's had Gus's opinions drummed/beaten into her all her life, and they will affect her actions and judgement whether she wants them to or not.
I still wonder if Gus might be an ex-Thrall; he won't talk about his past, and his "more Werewolf than thou" attitude do somewhat suggest that, almost as if he had something to prove.
Then again, he could just be a Werewolf Jerk: that's the most likely.
