He was not an innocent child getting picked on for no reason.
He was a grown man in his forties, a public figure, who chose to lie about his past, his qualifications, his job positions, his level of disability at various points in his life and who knows what else. He put all that information out in the public domain.
He took other people's work and passed it off as his own. He made his decision to not just lie once but over and over again.
He eventually got caught out and people began to ask questions. When he got caught out did he do the right thing and admit it? No. Instead he called his accusers racist, and in some cases got the police involved, in others sent legal letters. He accused students who complained about the poor level of teaching and supervision etc racist.
He continued to lie about anything and everything despite knowing that it was undoubtedly all going to come out at some point.
Did he think about quitting then, whilst he was ahead? No.
Instead he got a lucrative book deal on the basis of his unbelievable back story and continued to lie whilst going on various programmes and podcasts etc. He was more than happy to do that and take the fees from those things along with his considerable wage from Cambridge.
So when it did come out the unravelling of his lies was always going to be very public and immense. He knew that as he'd created the immense amount of lies in the first place, and he'd made those lies not just to a few select academics but to the world at large.
He had choices. He could have admitted he'd stretched the truth on some things, lied on others and faced the consequences of his decisions. He chose not to do that.
So no, the decisions he made at the end of his life, like everything else he chose to do in his life, is on him, not anyone else and any shame in this whole sorry saga is certainly not mine to bear.
