Since you said "pretty much," does that mean there have been exceptions? Also, other than the Bane example, the rest don't really sound like examples of Batman being broken. Are there examples of a Batman who had been subject to similar scale pressures as
BvS Batman? These include, in the span of a little over two years, the murder of Jason Todd, years of solitary and fruitless crime fighting, and a super powered alien invasion that caused 9/11 style destruction including of his own building and employees. What do you make of
this essay, for instance?
That's not how I remember his murder of Ra's Al Ghul in
Batman Begins or how he endangered lives by setting the monastery on fire at the start of the film. It's also not how I remember all the kills in the Burton films.
Yeah, at least in
BvS the killing and cruelty is challenged and portrayed as wrong. Batman can kill Ra's Al Ghul without any PTSD as a foundation, yet it's hand-waved away as insignificant.
BvS Batman doesn't believe he's not needed, though. As he says to Alfred before he goes off to fight Superman, he feels that stopping this threat is basically the last thing he can do to make a difference. It will be his legacy.
Then it's not a comparable situation, since Gotham clearly does need someone to fight crime still and with that crime and the threat Superman poses, Batman sees opportunity to still make a difference. Nolan's Batman, conversely, does kill without any narrative or character based explanation; so it's treated as okay and normal. He also crosses lines like using invasive spy technology that disturb Lucius Fox.
I see terms like irrational, illogical, low IQ, and idiot thrown around sometimes with regard to BvS Batman as if they are synonymous with psychological distress and immoral behavior. Since intellect has little to nothing to do with those aspects of a person, where are the complaints about his intelligence coming from?
