If I want to control you, I will tell you never to be selfish. I will tell you we are meant to live for the community, that we are meant to serve others and to never have selfish thoughts, lest we'd be led astray.
I will tell you exactly how you should serve others, I will give you the necessary orders and instructions. Pay taxes to me, do what I tell you to do, fight my wars for me, protect my throne for me, protect my money and power with your life, silence the critics for me; be my mob.
Do all this and you are living the right way. Serving others like the noble and civilized person you are. Well done.
Why would other people exist in my world, if not to serve me?
