Outlook, I understand your viewpoint many would agree and disagree. French philosopher Descartes argued that without divinity mankind loses it's purpose and with it, a sense of justice. The notion of divine retribution has been with us since antiquity.
Bamber has lost all his possible outlets for squirming out of his just punishment. It will come as no surprise that life imprisonment certainly has not taught him how to be contrite, remorseful, empathetic or even humble. The reason? He is a psychopath. Incapable of these basic human emotions. The kind of feelings that bond humanity together. A sense of 'doing the right thing' makes us feel good about ourselves and others who follow it. However, to a psychopath this makes no sense at all. Why should they do anything for anyone else if there is nothing in it for them personally? A reasonable question if looking at it flatly and logically, but we are human. We have a moral responsibility to each other. This is the language that the Bamber's of this world cannot understand. They are intensely self-centred, arrogant and callous, concerned only for themselves and view others purely for what they can get out of them. Such people in antiquity were called 'demons' who walked among us on earth 'sowing wickedness and iniquity' This was the birth of the 'angels and demons' stories. Later, they were deemed to be 'morally insane' and locked up in asylums. Later still, they were studied and conclusively labelled as psychopaths or sociopaths. A personailty disorder that made them anti-social and treat others as nothing more than objects to be used. The names may have changed, but not the meaning. Are we still dealing with demons of the past? In Bamber a man who willfully stood over the sleeping bodies of two innocent and defenseless children before he shot them repeatedly at point blank range in the head, just to enhance his own lifestyle, I believe we certainly are.
