"It seems Adolph had issues surrounding his mother and perhaps an uneasy relationship with his father. We think that this may have disturbed his emotional development..."
You don't say! Are we moving 'beyond good and evil'? Isn't there a level on which every mass murderer could be designated as 'insane'? How does an investigation or a court come to the conclusion that someone was suffering 'psychosis' when they committed mass murder? Was Stalin just suffering from a 'psychotic episode'? Where do we stop? To my mind, which as we know is sometimes prone to eccentricities, declaring Breivik as someone who suffered acute psychosis or schizophrenia is a terrible insult to those who are genuinely mentally ill and who suffer from unwanted 'voices', delusions or illusions over which they have no personal control and the vast range of mental illnesses in existence.
I know a few people who suffer from schizophrenia. None of them have anything like the kind of terrible hatred that Breivik had for people he sees as 'unfit' to live. Even though they suffer greatly, they have an enormous amount of love and compassion for others. Some would do violence or injury to themselves, but they would never inflict anything like this on anyone else. Genuine schizophrenics are left to rot in their homes without care and to wander about the community trying to deal with their 'voices' and behaving very oddly in the eyes of the rest of society. They don't methodically shoot 69 people and orchestrate an intricate terror plot. Who else are we going to let off for being 'insane' or 'psychopathic' murderers? Shouldn't Tony Blair be in an asylum by now?
