That's a good point. I suppose this highlights the difference between having power and having the inclination to use it. I'm not sure whether being an introvert makes someone less likely to be a trouble-maker, though. I've heard it said that it's the quiet ones we need to be careful of. I suppose the point is, IF an introvert happens to have an evil streak, they are more dangerous than an extravert with an evil streak because they are more likely to hatch their evil plans in private.
