I think we can all agree on "damaged," ita, but "psychotic" seems a bridge too far.

"Psychotic" has very specific diagnostic meaning. It's for people who hear voices that tell them to do things and other gross misapprehensions of the consensus reality. Batman deviates from the social norm considerably, but he can readily put on Bruce Wayne's tuxedo and mingle and socialize as much as he wants without worrying about the bugs under his skin or whether the CIA is controlling his thoughts.

Do you disagree with the Britannica definition, or am I interpreting it too loosely?

Not being a doctor, I don't know what the dif is regarding psycosis and psychotic, if there is one. You make a lot of points of which I kind of agree with you on.

any of several major mental illnesses that can cause delusions, hallucinations,

Batman is very grounded in reality, doesn't even really believe in magic (should read some of his interchanges with WW in JLA).

serious defects in judgment and insight,

Okay, maybe training children to jump off of skyscrapers while doing a handstand then going out with them to do it and get shot at...

defects in the thinking process, and the inability to objectively evaluate reality.

They don't call him the world's greatest detective for nothing.

doesn't even really believe in magic

Dude, there, right there is a red flag in a universe with Zatanna, but I should probably read the exchanges, because I can't believe they'd have him take the stance I'm reading that as.

Should have been clearer, many of the issues I've read have him and WW arguing about gods and magic and their validity in the real world. Usually when they're sparring. Blanket stating he doesn't believe in magic was oopsy.

That's canon.

Is it sane? Is it compliant with our reality?

Well, maybe an exaggerated sort of sane, if you will. Bruce Wayne would hardly be the first person to put on a metaphoric mask to deal with the world, after all. But then, some other writers have had good takes on it.

The JLA story where Batman and most of the rest of the League were seperated from their alter egos was actually rather telling--"Batman" was an emotionless void, all skill skill and control, but no there there. Bruce was an empty, vapid plaboy with immense rage that he was unable to focus.

The end analysis, ala Plastic Man of all people, was that if you separate Bruce Wayne and Batman, you don't just get a psychopath and a playboy--Bruce Wayne needs all of Batman's training and discipline just to keep his own anger from consuming him.

ita, I think you are interpreting too loosely a definition that already lacked the rigor you would find a professional diagnostic manual.

I found Elseworlds really helped me to nail down some core Batman, just through repetition, helping me understand what stuck to the mythos, what made it Batman when everything was mutable.

This may explain my Elseworlds addiction. It's a serious sickness. I'll even read the crap ones, because hey! Elseworlds!

Another vote for Nightwing as discriminate man-ho (you want indiscriminate? Roy.)

Yep. Dick's a very physical person who attempts to forge emotional connections. Even when it's not sexual, it can be misread as such. Roy's a very physical person who does his best to avoid them with females who are not Lian and is pretty open about it.

Dick's intent may be more noble, but I suspect Roy winds up being a hell of a lot less confusing for the women involved.

It's a serious sickness. I'll even read the crap ones, because hey! Elseworlds!

Elseworlds, I love it. Krypton on Earth, ever read that one?

The end analysis, ala Plastic Man of all people, was that if you separate Bruce Wayne and Batman, you don't just get a psychopath and a playboy--Bruce Wayne needs all of Batman's training and discipline just to keep his own anger from consuming him.

That's one of the better JLA storylines, at least in terms of Bat insight. And also J'onn insight.
