The Second Rule is that the greatest harm can result from the best intentions. It sounds a paradox, but kindness and good intentions can be an insidious path to destruction. Sometimes doing what seems right is wrong, and can cause harm. The only counter to it is knowledge, wisdom, forethought, and understanding the First Rule. Even then, that is not always enough.

many people must be ruled to thrive. In their selfishness and greed, they see free people as their oppressors. They wish to have a leader who will cut the taller plants so the sun will reach them. They think no plant should be allowed to grow taller than the shortest, and in that way give light to all. They would rather be provided a guiding light, regardless of the fuel, than light a candle themselves.

I am dead. Only vengeance can restore me! Only victory can return my life to me!

People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it's true, or because they are afraid it might be true. People’s heads are full of knowledge, facts, and beliefs, and most of it is false, yet they think it all true. People are stupid; they can only rarely tell the difference between a lie and the truth, and yet they are confident they can, and so are all the easier to fool.

There would be nothing I could do to you that would harm you more than what you're already doing to harm yourself...You are never going to amount to anything. You will always be the worthless muck people scrape from their shoes. You only get one life and you are wasting yours. That's a terrible shame. I doubt you will ever know what it is to be truly happy, to achieve anything of worth, to have genuine pride in yourself. You bring it all on yourself, and I could do no worse to you.
