Well, I saw the Brock thing coming, but I can see why you would say it's bad for the character. Walt as a person is completely indefensible now; he no longer has a leg to stand on with that "it's for my family" shit. I guess the writers did put themselves in a bit of a bad spot, though. That's probably why it looks like this season is less centered on the moral ambiguity stuff and more about just tying the loose ends of Walt's inevitable demise. I'm going to enjoy that demise, considering the fact that Walt is more of a villain now than anything.
