Sons of Anarchy has always considered itself a modern-day morality play. The club doles out unlawful justice, and usually punishes enough really bad guys to make us feel like they are the good guys. However, the peripheral damage that the club is responsible for took us, the audience, to a breaking point early in season 6.
Some critics were concerned at the beginning of this season because Jax didn’t appear to feel enough remorse after the school shooting (which was made possible because the club ran guns). I argued that this was in keeping with the tradition of morality plays–because we are supposed to judge and question what constitutes virtue and vice, and Sons of Anarchy is forcing us to do that.
