The media portrays the image of the killer as being a psychopath, when actually psychopaths are in the minority of homicide perpetrators.

Most homicides are not planned, are not done in cold blood, and the perpetrators are very often not irredeemably evil.

I suppose I am biased because my partner (who I knew for five years before his crime) is in prison for manslaughter due to a psychotic break triggered by a combination of magic mushrooms acting on an already mentally ill mind.

Was the crime heinous and the pain he caused irrevocable to the loved ones of his victim? Absolutely.

Does that make my partner an evil person? Absolutely not. And yet much of society would prefer to see all killers as evil heartless psychopaths. Some are (Ted Bundy for example) but many killers are people just like you or I. With the same mix of problems and flaws as the average person, no more inherently evil than the average person.
