Personally, closer than you perhaps, but still very far from being an expert, I think he's not psychotic. But still a very sick man, narsisistic and what we used to call a psychopath which does not make him insane and as such he can be sentenced to prison, probably in the form of "forvaring" (custody), which may keep him incarcerated for an unspecified time, even the rest of his life. Depending on how long he's considered dangerous.
