“Schizophrenia, if thats what it is, often settles in during late adolescence.”
Yes, this is true. But is there any reason to think this kid was schizophrenic or otherwise insane? The girl rejected him, he killed her and a bunch of other people, but then his nerves failed him and he did not kill himself as he had planned to do. That’s vicious and evil, but is it indicative of insanity?
Unless you want to say that all mass murderers are insane. But, to me, to say someone is insane means that they are detached from reality in some way. Like when Hinkley shot Reagan in an effort to impress Jody Foster.
