George Blake's motivation sounds naive and he pretty much admits wasting his life

Since his dramatic escape from Wormwood Scrubs prison in 1966, Blake has lived in Moscow. He is a colonel in the KGB, with the Order of Lenin and a government pension, living in a spacious, rent-free apartment.
The money will probably make little difference to Blake. It was announced last week by his Russian publisher that he is seriously ill. He is the last living example of that group of ideologically motivated British spies (Blunt, Philby, Burgess and Maclean among them), drawn by idealism to work for the Soviet Union, and one of the few to live long enough to see the expiration of their hopes for a communist world.
In 1948 he was chosen to go to Korea to establish a network of agents. While he was there, as vice-consul in Seoul, the Korean war broke out and the capital was overrun by the Communist North Korean army. In the company of other diplomats and missionaries, Blake was evacuated north and interned and witnessed what he claimed convinced him that he should work for the other side: "It was the relentless bombing of small Korean villages by enormous American flying fortresses. Women and children and old people, because the young men were in the army. We might have been victims ourselves. It made me feel ashamed of belonging to these overpowering, technically superior countries fighting against what seemed to me defenceless people. I felt I was on the wrong side ... that it would be better for humanity if the Communist system prevailed, that it would put an end to war."
However, he has no regrets for his support of Communism: "The Communist ideal is too high to achieve ... and there can only be nominal adherents to it in the end. But I am optimistic, that in time, and it may take thousands of years, that humanity will come to the viewpoint that it would be better to live in a Communist society where people were really equal."
