He doesn't come off as a maniac at all. I rather enjoyed his philosophy and his success speaks for itself. He sold a crappy tasting drink for more money than anyone would have imagined possible. The guy is brilliant.
Doctor No said, in the same soft resonant voice, "You are right. Mister Bond. That is just what I am, a maniac. All the greatest men are maniacs. They are possessed by a mania which drives them forward towards their goal. The great scientists, the philosophers, the religious leaders - all maniacs. What else but a blind singleness of purpose could have given focus to their genius, would have kept them in the groove of their purpose? Mania, my dear Mister Bond, is as priceless as genius. Dissipation of energy, fragmentation of vision, loss of momentum, the lack of follow-through - these are the vices of the herd." Doctor No sat slightly back in his chair. "I do not possess these vices. I am, as you correctly say, a maniac"
