Suspension of Disbelief.
Did you know Gotham has the Death Penalty?
Now of course, this doesn’t impact most of Batman’s foes, as they’re all nutso. Indeed, it goes a bit towards explaining why Arkham is so full –clearly pleading insanity is a proven way to avoid the current in Gotham. It does make one wonder though – how many people has The “I Don’t Kill EVER” Batman sent to their state-sponsored death? Ooo… and what if he were wrong?
Hmm. This may be less a WWTT and more an idea for a pitch…
