It’s funny that no one dares examine the true root cause. In my opinion it will never go away until we face the hard facts and recognize what was going on in this man’s head. It’s very convenient and easy to dismiss him as pure evil, or a psychopath, or the like. And attempt to try to see him as anything other than that is met with shock and horror and is generally just unacceptable as it gives the impression of sympathizing with him.
Do we honestly think he’s pure evil and relishes in seeing his victim’s pain and suffering? Does he completely lack any form of empathy or caring and is he totally numb to the effects of his crimes? Is he a sociopath? A psychopath?
I highly doubt it.
