See, I'm not sure how or why but I think I've developed a disconnect of sort from Walt and his actions. I think it probably stems from the fact that I first started watching Breaking Bad as a study in a media studies class, so spent ages analysing the show and his character - something that I still do (it's probably actually my favourite part of the show). The one thing that stuck in my mind was an interview with Vince in which he said something about the entire series essentially being an experiment of sorts into how long it would take him to transform Mr Chips into Tony Montana. I think because of this I've always approached the terrible things he's done in this nearly comic way. I think if I didn't have this view, I'd probably hate Walt much more. As it is, I just love seeing how terrible he can get. Jesse is my favourite, though, definitely the protagonist in many ways. He's done some pretty bad stuff, too, but he has a conscience, he's the one who has grown the most throughout the show (whereas Walt has less grown and more self-corrupted).
