Psychosis

"Why Adam Lanza did what he did is apparent from your article: untreated psychosis. Psychosis is a brain disease. In some people it can create a private world of misperception and misinterpretation, of danger and obsession, of an imperative for action that has no relation to external reality. 

If recognized and treated, psychosis may be a painful and debilitating illness, but not one that is dangerous to others. The failure to speak and write clearly about psychosis, instead using such vacant euphemisms as “disturbed,” impedes our ability to care for its victims and protect the public."

Lanza was a 20-year-old mass shooter at Sam Hook Elementary School, where he used to attend as a kid, killing over 20 children and some teachers after shooting his mother dead at home. Lanza was diagnosed of having Asperger's syndrome. The human brain is a dedicate organ and highly vulnerable. After seeing all the defense (a misnomer, really) mechanisms---including denial, self-projection, blaming others, denigration (including self-denigration, but this inward denigration is rare), cruelty, aggressive lashing at sources of discontentment---exhibited by monkeys and defective humans, I concluded that a clear-eyed acceptance of self and others is essential for mental health. If we have to act out, it's safer to do so via displacement and sublimation. Monkeys and defective humans tend to have an unduly inflated sense of self despite glaring realities, and hypocrites always present a self that is the opposite of what it is. All these sorry pieces of being are not comfortable with realities, especially the realities as to who they are, and the discrepancies between their aspirations and actual accomplishments. They live a life no different from that of barnyard animals: eat, shit, sleep, have sex and offspring, and then die. They leave nothing of themselves behind that is contributory to human culture or advances---they are not good enough, yet they proudly present a false front of happiness and contentment and they are full of excuses as to why they have not been able to do as well as others have done ---they never once entertained the thought that their failure to do so lies at the their lack of ability and/or drive. Monkeys and Pygmy chimps have excuses. Real humans have strong desires and drives and determination, on top of having a better brain. There lies the differences.
