Ol Jock- I'm curious how you came out sympathizing more with walt in that conversation (or at least understanding POV)? not trying to flame, but at this point in the show, it's clear to me that walt is full of crap, manipulating everyone only to what he wants (without any consideration for their needs, including Jesse, Skylar, Hank, etc.).
That discussion was indeed fantastic, and while a non-omniscient person might think that walt was making good points, it's been very clear for awhile that walt has done terrible things to his family and those close to him. maybe not directly, but his actions have always had dire consequences for people he says he cares about. and when those people express their displeasure for being put in those situations, walt turns the manipulation up even more. All so he can feel better about himself or pump up his ego.
Skylar, Jesse, etc. are no saints, but they at least have shown some humanity, some restraint and some concern for others. Walt has shown no concern for anyone but himself (despite his protestations that he's doing this "all for his family").
