Bill has worked very hard to cultivate his image; Most people don't realize he came from an incredibly wealthy/powerful banking family.
The origins of Microsoft are also very interesting. The IBM deal, which got the company off the ground can be wholly credited to Bill's mother.
He has always been very open about the fact that the goal of his health programs has been to reduce the population in India, Africa and the developing world.
It is difficult to say if he is a hero or a villain, but I don't want to be subjected to his vaccines, passports or climate-change plans.
