Breaking Bad's Walter White is one of television's most iconic antiheroes, and several moments from the show will test viewers' allegiance to the character. Walt's actions become increasingly dubious over the course of Breaking Bad, so it makes sense audiences might question his motivations and their validity. Walt starts the series as a mild-mannered chemistry teacher who enters the criminal world to pay for cancer treatment and take care of his family. Although he begins as a relatable lead, his character's likability wanes as he justifies increasingly immoral acts.
