Under the M'Nagten Rule as has been adopted and modified in most English-speaking jurisdictions, a person is legally insane if he or she could not under stand the criminality of his/her behavior at the time of his/he acts. It's actually almost impossible for a psychopath to be declared legally insane (e.g. Jeffrey Dahmer), as they understand their behavior is criminal. You could be psychotic and therefore unable to distinguish right from wrong.
I meant if it is still possible to be legally insane without being psychotic, like neurogenative and neurodevelopental disorders are so severe that you are completely unaware of your actions.
For example, you committed any crime, but then you don't understand why you are being punished, and even after the judge explained to you, and in the cell, you are yelling and asking for help, because you completely don't understand what is going on and you are scared, no psychosis involved, just completely bad neurology of awareness.
But, what I described looks more like incompetent to stand trial, than legal insanity though, you do have a point.
