But in talking about illness: if a person with AIDS knowingly goes around sleeping with as many people as possible with the self-professed intent to further transmit the fatal disease, that person’s behavior is criminal.

This person had sociopathic behavior. Sociopathy is not illness, it is, in its essence, hate. Hate, in turn, is no more than willful thoughts to destoy (in this case, thoughts to destroy other people).

An example of mental illness is when the brain is missing sections or is otherwise malformed.

If there is such a thing as a “chemical imbalance” in the brain (the supposed cause of so many mental illnesses), I would love to one day see a person with a “chemically balanced” brain.

Emotions (love, hate, etc.) produce chemicals in the brain; an example being the joy we feel when we’re in love (releases of endorphins). Emotions make us chemically imbalanced.

If that person didn’t control his emotions to the extent that he decided that he must kill, that is an example of human behavior that we should try to prevent from ever happening again, rather than “understanding the mind” of the murder as the media wants to do (and force down our throats).

“Blame lays in one place: the evil heart of that person.”

Evil heart? A heart is a vital organ that circulates life-giving blood throughout the body. Based on the documented evidence of police reports and an attempt at involuntary hospitalization plus the NBC videos, it appears that Cho was mentally ill. Mental illness is an illness. That is why US courts may declare an accused unfit to stand trial or a jury may acquit by reason of insanity. Cho wasn’t evil; he was mentally ill.
