Yes, because without Bear, they couldn't get their A-Game going with the others, perhaps? They're thinking from a manipulative-grabbing the camera's attention point of view. Better a prick in the house in which they can get their own drama involved (although they don't have to get themselves involved, Bear just picks out who he's going to be a arsehole to at that moment). They, along with we, don't know who on earth they could dramatically interact with because Bear and BB has never given a chance for the other housemates to be seen other than an extension of the Bear story line. The other housemates are not like Aubrey or Renee (or Bear, Lewis, Chloe, & Marnie, in fact) in which they have their come from the reality TV culture - they are just pig sick with the psychological cancer Bear spreads over them.
If the other housemates were allowed to shine, only then, would I be informed enough to make the judgement that yes, they were in fact boring as crap and not just miserable and low because of one bloody man causing grief wherever he goes and clearly being allowed to. Shockingly, even Frankie is not his usual self but, he's not acting like the other reality TV famewhores at the moment. Aubrey and Renee are thankful for Bear because he also makes their story lines relevant and they don't have to go out of their own way to be bitches themselves to the others to keep them in the limelight.
