The biggest thing one needs to remember whenever you judge Walt is that he believes his own lies.
The best example of this is his school speech after the plane crash. I don't think he's such a sociopath that he is incapable of feeling guilt, because that's what he feels right then and there. But as he goes on, he keeps trying to rationalize the number of deaths, trying to frame it as not that big a deal in the grand scheme of things.
Whats important about that scene is that it's completely unprompted. No one in the whole world considers him culpable for those deaths, even the majority of the audience. He has no reason to be talking about it the way he does. But he does so because he personally does feel it's his fault. And his response to that feeling is to tell himself "It's okay, just look at how small and meaningless this truly was".
So when he tells his family that he's doing it for them, tells Jesse or some random bar dude that it's about protecting your family, tells whoever that his motivations are unselfish, he's honestly believing what he is saying...but that doesn't make it necessarily true.
To bring this back around to BCS, I actually think that this makes Chuck the biggest Walt surrogate in the show. He's a control freak who believes himself to be benevolent. That he's only protecting the law and the people from Jimmy's insane disregard for rules. And there is honestly a strong case to be made there, given Jimmy's almost pathological apathy and disregard of rules....but it's also impossible to dismiss the personal egotism and resentment Chuck feels for Jimmy. And it's nigh impossible to seperate them, since Chuck has extreme difficulty seeing himself in the wrong at any time.
