Well, I think that's one of the good things about that story, that both the Doctor and the Brig have a point, while at the same time also being blind to some of the consequences of their actions, and that neither of them can conclusively be shown to be in the right. I guess we're supposed to side with the Doctor, but the script allows us to see the Brig's point as well. I don't think you'd get this in many other eras of Who (or indeed, in the rest of the Three era), so it's another thing to be said in favour of Season 7, which had a few moments like that.
