There was this story in JLA a few years ago (I'm sure someone can provide issue numbers, I only read this in a borrowed collection) in which the Bat-computer is hacked by Ra's Al Ghul and he steals the contingency plans the ever prepared Batman had put in place in case any or all of his super powered buddies went bad and he had to take them down.
It's a decent story and of course our heroes win the day. They are a little uncomfortable with Batman for preparing for this kind of eventuality, but they can't escape the hard fact that it's a reasonable thing to do given how often they are individually or collectively brainwashed, possessed, replaced with evil duplicates, and all the other problems with which superhero life is fraught. None of them suggest that the security on the Bat-computer needs a little upgrading.
Something like a year later, after Batman has spitefully kicked out Steph for doing not only what any other Robin would do but I'm 95% certain has done in similar circumstances, she tries to prove herself to him by hacking the Bat-computer and using one of his plans. It's an incredibly clumsy plot constructed purely to make Steph The Flawed Hero Who Must Give Her Life to Atone for the Mistake She Made. I saw where this was going in the first issue and couldn't bring myself to follow it to the end. But I'm betting nobody suggested that Batman upgrade the security on the Bat-computer.
And then we come to the OMAC project. Batman comes up with a new scheme for defending against his super-buddies on the off chance they go bad. Can you possibly make a wild guess what happens? Yes, one more time someone hacks the bloody Bat-computer and steals these most top secret and dangerous plans, reprograms the OMAC control system, and uses it to kill a lot of people.
Batman surely has some responsibility here? Isn't he in the same position as Steph, only with a higher body count? How come Brucey doesn't get to sacrifice himself nobly to atone for his mistake? But no, you see Batman doesn't even acknowledge he has done a thing wrong. In fact he manages to get on his high horse and be disgusted with Wonder Woman for killing Max when she is given no alternative, even while the fruits of his criminal negligence are killing people by the thousand.
Nobody even suggests that his clever schemes (and doesn't anyone think that a plan that involves converting innocent bystanders into cannon fodder is fundamentally flawed?) have caused far more damage than the potential dangers they were designed to guard against, or that maybe it's time he stopped trying to think of ways to hurt his friends, or if he really must do so, he write these plans down in a notebook and keep it in a big safe at the bottom of the Batcave, rather than publishing them on the internet.
