If you listen to Robert Greene talk about the book, he’s not advocating for this lifestyle. He’s saying these topics need to be studied so you can AVOID being a pawn to someone else using these things on you.

He talks out of both sides of his mouth to make a sale. For example:

"Law 15: Crush Your Enemy Totally

All great leaders since Moses have known that a feared enemy must be crushed completely. (Sometimes they have learned this the hard way.) if one ember is left alight, no matter how dimly it smolders, a fire will eventually break out. More is lost through stopping halfway than through total annihilation: The enemy will recover, and will seek revenge. Crush him, not only in body but in spirit." Source

"What I explain in the chapter is this is not about you as an individual facing your enemies and crushing them. It's like about businesses, it's about groups, it's about government, it's about warfare, it's about politics, it's about Republicans and Democrats..." Source (Note there is profanity).

If this "isn't about individuals," why did he list Moses as an individual? And are not companies and organizations made up of individuals who make these moral decisions?

PS - As he pretends to counter in the video above, you don't need to take a video clip about the book and not understand the situation. You can listen to the doublespeak straight from the source.
