you mean the shoplifting? IIRC in the first season everyone but Skyler 'breaks bad', or does something slightly illegal (in comparison to walter and jesse). Marie shoplifts. Walt Jr gets someone older to buy him alcohol. Hank with the Cuban cigars. Skyler has sex next to a police car, I suppose that's illegal. Maries storyline seemed to have a purpose but it disappeared and reared its head again early in season 4 when she steals stuff from an open house. It had no real resolution. IMO it was just highlighting the different moral grounds every character stood on.
