Don Brash's moral bankruptcy

Fighting Talk's Lyndon Hood has a throwaway paragraph which exposes Don Brash's moral bankruptcy over human rights:

And while there’s a lull in proceedings I’d like to mention that Dr Don Brash helped set up the Freedom Foundation, a group of New Zealand business types supporting Amnesty International (its other patron is the deputy chairman of Transpower). Recently in question time this same Don Brash was taunting the Government for not immediately taking up his offer to help remove prisoners’ entitlement to compensation for human rights abuses.

Is there any belief that Brash won't sell out for political advantage?
