brainiac - // What puzzles me about this is what did he get out of it? Was it to do with the money he was paid for performing the operations - many of them were done at a private hospital? Pure self-aggrandizement, feeling he was powerful and unassailable? Or maybe he was in the grip of some strange Munchausen-type syndrome?
It beggars belief that he got away with it for so long, and I'm sure - as the enquiry has said - that there must have been colleagues who knew, but said nothing. //
I would suggest it is the power thing - I can do what I want and no-one can stop me.
It's a mental aberration that strikes some individuals, but they are usually not in position to exercise it.
Some, such as surgeons, and indeed priests, who are revered and to whom normal rules of accountability are allowed slide, are able to exercise their God persona, to the detriment of others, and the increase of their sense of power and infallibility.
Some will have known, but felt too cowed, either by the force of his personality, the realisation that they were unlikely to be believed against such a powerful individual, or the worry of risk to their own career prospects, or even job.
It all conspires horribly to allow a situation like this to occur.
