Projection. Sure it is “overused” to the point of meaningless but as I trudged through Freud because I had to to get my BA, but I do believe projection is what you are after. I have mixed thoughts on Freud so I never took him too seriously. That said, if you think about it “underhanded” people or people who have a proclivity to underhandedness are going to see signs everywhere they look that someone else is trying to gain advantage on them in the exact same way they are attempting to gain advantage on others. An extortionist sees extortion everywhere he looks, an adulterer sees adultery everywhere he looks. The worst thing that could happen to them is to be taken advantage of in the same way the are taking advantage of others.
He who looks behind the door is he who has stood there before.
