Well, if it was premeditated, it probably wasn't schizophrenia, since most schizophrenics suffer a severe lack of volition and ability to follow through on their plans, which is why you see so many of them living in boxes and muttering about the government instead of going on shooting sprees. On the other hand, there are dozens of similar disorders that leave people delusional enough to kill dozens of innocents that they don't know.

And psychopath/sociopath is an actual clinical term, and is used to refer to someone with antisocial personality disorder, which this kid clearly didn't have. My point was that yeah, he was insane, that's the sad part. He was as much a victim of his insanity as the thirty people he killed. He committed murder, yes, planned it and was ruthless and vicious about it, yes, but all of that was because he was ill. With anti-psychotic medication, hospitalization, and therapy, he could have lived a mostly normal life in which he would have been no harm to anyone.

I can understand loathing what he did, but to write him off as "absolutely insane" is unfair. Not just to him, but to everyone who has struggled with and persevered against a severe mental disorder, as preachy as I know that sounds. :\ And I think I'm done ranting now, but whatever.
