The idea that wanting to save the world when you actually have the ability to do so is somehow not just a fault but a mental disorder really, really disturbs me.
Also, the current Batman predates most other superheroes, so the argument that dressing as a Bat is sane because of that is silly. It’s sane because he had a rational reason to do so–to create an alternate identity to protect himself, and for it to be themed on a night-time creature. It’s just a freaking hat/mask and cape, after all.
