Mao the Uebermensch

I am reading Mao: The Unknown Story, and I think it's great. Because of its 600+ page length, however, you might want to take a pass, but I'll summarize. I think the following quotation from a 24 year-old Mao gives explanation to the entirety of his career:

I do not agree with the view that to be moral, the motive of one's action has to be benefiting others. Morality does not have to be defined in relation to others...People like me want to .... satisfy our hearts to the full, and in doing so we automatically have the most valuable moral codes. Of course there are people and objects in teh world, but they are all there only for me.
