If we ever need to understand anything about society, it's the idea that we have a justice system that's supposed to apprehend criminals with reasonable use of force, and yet our media thinks they all need a violent death.
The other irony is that is that on the few occasions when they really, really should kill the villains, they often don't. I mean, after Joker / Penguin / Poison Ivy etc have escaped prison / asylum for the 3rd time to wreak havoc, death and destruction, someone should have learnt the lesson. The fact that Brucey keeps putting them back in with the inevitable knowledge they'll be out in a jiffy makes Batman the worst fucking idiot to run round in a cape.
