Did I ever tell you what the definition of insanity is? Insanity is doing the exact… same f**king thing… over and over again, expecting… sh*t to change. That… is crazy; but the first time somebody told me that… I dunno, I thought they were bullsh*tting me, so boom – I shot him. The thing is, okay… He was right. And then I started seeing: everywhere I looked, everywhere I looked, all these f**king pricks, everywhere I looked, doing the exact same f**king thing… over and over and over and over again thinking: “This time, it's gonna be different; no, no, no, no, no, please… This time it's gonna be different.” …I am sorry, I don't like the way you are looking at me… Okay, do you have a f**king problem in your head? Do you think I am bullsh*tting you? Do you think I am lying? F**k you! Okay? F**K. YOU! It's okay, man. I'm gonna chill, hermano. I'm gonna chill… The thing is… alright, the thing is: I killed you once already… and it's not like I am f**king crazy. It's okay… It's like water under the bridge. Did I ever tell you the definition… of insanity?
~ Vaas Montenegro giving his famous "definition of insanity" monologue to Jason.
This category is for villains who have any type of psychological disorder and can be deemed as mentally unstable or villains suffering from mental disorders such as schizophrenia and psychosis. In addition, a villain who is perfectly meaningful, coherent, and stable can still be qualified as mentally ill if the evil deeds they perform are extremely fiendish and malevolent, the reason being that no sane individual would think it acceptable to take villainy to the degree that they do.

These characters are also Tragic, since the trait of being mentally unstable is being unable to tell right from wrong, examples of which include Bae Su-mi, most Yanderes, and Anniyan. Nevertheless, some can also be Pure Evil, such as Henry Evans.

Note: not all villains are mentally unstable when they first appear. While some are, others who were sane to begin with suffer experiences that causes their sanity to snap, like Andrew Detmer and Lucy. The primary causes for this are prolonged abuse and humiliation. A severe-enough degree of fear can do it too, but less commonly. Also, while psychopaths/sociopaths does qualify as a mental illness, not all villains who have mental illnesses are psychopaths/sociopaths, so if you have a villain that is either explicitly stated to be that or otherwise has been clearly depicted as being that, use the category Psychopath instead.
