Have him sit on chairs strangely, like one leg always thrown over one of the arms, or even just have him perch on the seat like some sort of bird. As part of the realising 'holy shit I'm kind of heading out into insane territory here', have him order his lieutenant to stop him if he tries doing whatever his compulsive thing is, like eating the fingers of people he's killed or something insane like that. For bonus points, have him fully aware of the fact that he's probably going completely insane and his most trusted lieutenant should be his sort of 'moral compass', stopping him from doing things that are a little TOO insane. When the PCs inevitably kill this lieutenant, the villain goes COMPLETELY off the deep end. An example of this is Dio from Jojo's Bizarre Adventure: His 'evil plot' in season 3 is actually extremely admirable: He wants to create a perfect world for all Stand users, where they can live freely and use their powers as a sort of system of ruling nobles/police force. However, he's well aware of the fact that he loves to kill people, hates people who foil hi 'brilliant' plots and has a HUGE ego, so he actually asks one of his followers (one who isn't being mind controlled and is still absolutely fanatically loyal) to keep an eye on him and stop him if he looks like doing anything stupid, in case he 'gets distracted'. Come to think of it, Dio is a pretty fucking amazing villain.
