I'm starting to wonder if Joker really belongs there either. Like he does have some sort of mental illness, there's no denying that, but every crime he's done is clearly premeditated and done with the intent of killing people.
In the legal sense of the word, he's not actually insane. He's fully aware of what he's doing, and has no remorse for it either.
You'd also think that eventually they'd try him in a national court instead of a state court and just give him the death penalty. Of course, that's not much of a story, is it...
No, you are right about The Joker but insane is a legal term. You can go by the Paul Dini/Alex Ross origin. In this he was a gangster who liked to kill people, do bad stuff but aside from that normal for the most part. After his "accident" life continued but when caught it was "oh I'm crazy so you can't take me away to the big house" kinda deal because this Joker was very intelligent. Think Jack Nicholson Joker where before the accident you don't see anything abnormal or strange about him per se.
I think Jervis Tetch would qualify.
Definetly, as Jeph Loeb describes him in The Long Halloween as "Delusional. Schizophrenic. Homicidal."
And from Ed Brubaker "Jervis is obsessive-compulsive, and highly delusional. He's got an immature self-image, so he identifies more with children than adults. Oh and he's a genius, too."
Also noted in Gotham Central is Tetch will use rhyming as a defense mechanism. Tetch also has a obsession/fixation on hats. In Secret Sic he will not eat a piece of food without a hat on it and isn't interested in the sight of Knockout naked, because she isn't wearing a hat.
Everything in Tetch's life is an allegory to Wonderland, it's the only way to get through to him.
Yeah, Joker is a just a psychopath, there is no evidence he is actually criminally insane.
Sociopath, not psychopath
Penguin, Catwoman and Black Mask (though people might class him as insane for murdering his parents and carving his mask from his father's coffin (?)) They are the ones who wouldn't get past an insanity plea.
What if you count DeVito Penguin? hehe. Yeah Black Mask does have some issues and displays some umm behavior like using torture to get what he wants as they mentioned in Arkham Origins. Meanwhile, Catwoman is a character of interest to me always.
She comes off as something of a adrenaline junkie or something to me. Is she that interested in having the diamond or the chase after the diamond? She definitely has a few screws loose in that horrible Burton film but I digress. What if we look towards TAS which follows the comic pretty closely for the most part on the episode "Catwalk". Here she misses being the Catwoman but threw out the costume because of the law, doesn't want to get caught again. But Scarface strikes a deal with her to steal some jewels for him and insists that she misses the life, Scarface is right, she does miss being Catwoman. So of course she puts her costume back on and pulls the crime, but Scarface screws her over making her completely take the fall. She won't tell the whole story to Batman (ooh lying, how nice). Later on when the full story breaks out she says she knows what she was doing is wrong but did it anyway. I think this fits with being incapable of controlling your own actions. But it gets worse, she kills Scarface (well just a dummy, no biggie) but then goes after the weak and timid Ventriloquist trying to kill him. Of course Selina has been prone to kill but not like this.
I don't know, I know it's just one episode but overall she made some ****** decisions. She is aware of the consequences of her actions but doesn't care, the thrill makes up for it. She even knew she shouldn't of gotten mixed up with Scarface, but did it anyway. This sounds like sociopathic behavior to me. Plus, she refuses to let Batman truly help her, who wants to help her.
Sure, maybe she's not crazy and just stupid I dunno, feel free to reign if you want I don't mind.
