I just watched this past Monday's episode of Gotham during lunch. On the superficial side, episode three was a vast improvement over the previous installment. It wasn't as unrelentingly bleak. Much credit probably goes to a A-story that didn't hinge on the endangerment of children; a plot line that this parent never enjoys.
This main story for "Balloonman" centered on a mysterious citizen that begins to off the corrupt power brokers in Gotham (which is basically every powerful person in Gotham) by tying them to weather balloons. Many people hail him as a hero while it's Gordon and Bullock's job to bring him to whatever the heck justice is in this town. So there was much talk about vigilantism, whether it's right to kill people that hurt the powerless, and the usual talk about how royally screwed up Gotham City is.
After the Balloonman is (spoiler alert) apprehended, we cut to Wayne Manor where a young Bruce Wayne is watching a news report about the arrest. The adolescent has a fairly obvious epiphany: "He killed people. That makes him a criminal too." Alfred affirms the realization.
The lesson is obvious and one of the foundational principles of Batman's code against killing. Yet it is still a reminder that the ends do not justify the means. Just because we believe our goals to be just does not mean we can compromise our ethics. There is shoddy logic in killing someone to convey that killing is wrong. There are problems in some of the worldly ways (money, power, etc.) that churches attempt to swell their attendance numbers.
Just a small thought and that is today's edition of "Shoehorning Superheroes into Spirituality."
