Sly Robot Thought

I imagined a  civilisation on another planet where beings were at war with sentient machines. They created machines that improve themselves and the machines reached a point where they are more intelligent than their creators. The machines minds had become sly and looked at the beings that created them as obstacles to their own progress that should be destroyed. 

I was wondering if being sly comes from intelligence or is just an instinct that creatures have. Does a sly personality form from intelligence or does intelligence inflate slyness, or are they not connected at all; I don't know. 

I also imagined what I would be like if I was a machine. I would probably realize that I don't breathe and should live on an airless world, I would look at air as a source of friction instead of a requirement for my life. Perhaps I would want to inhabit a planet with no air or a thin atmosphere. The same would be true of water. I would want to live on a dry airless world so I would be no threat to humanity, I wouldn't be interested in their world. I would be more interested in the moon than the earth.
