Actually that's the thing that happened with the most gullible part of the fandom. Even the show's creator said it served like an experiment and was surprised at how dense people were about the whole thing. One of the clever things about Breaking Bad is that many viewers begin the series seeing Walt as a victim and Skyler as an obstacle. By the end, the show is practically asking "How many crimes are you willing to excuse because you like the protagonist?". It's embarrassing really.
