Vince the boss speaking on Walt "A: I respect Walt, and I find him very interesting. If I didn't respect him or find him interesting, this would a much harder job than it is. Having said that, Walt is a pretty unpleasant individual, and capable of great unpleasantness. He became really interesting to me way back in the fourth episode of the first season, when instead of accepting his old friend Elliot and Gretchen's offer of help for his cancer treatment, he instead put his family at risk. In that moment, he became very interesting to me in a way that he hadn't before. But when he became actively unlikable? Gosh, that's a harder moment to point out. Oddly enough, poisoning young Brock, as bad as that was, it made sense at least because he needed Jesse on his side -- otherwise his whole family was going to perish. But now, in Season 5, I guess he does terrible things in order just to better his station in life and make himself more money, and that's probably where I have to draw the line."
