'Evil' behavior, or antisocial behavior in general, is almost always caused (or exacerbated) by truama, and as so, it is the result of a distortion of cognitive functions. So there is no way to accurately specify the cognitive preferences of an indiviual effected by it.
For instance, PTSD is just such a distortion. It has specific features, and may vary slightly based on I/E, but not much. This means that the effects of truama are independent of cognitive function. Usually the person goes into a fight/flight mode of sorts, which represents a more infantile way of dealing with the world.
So can NF's be Evil or antisocial? Of course. They respond badly to truama just like to everyone else, maybe moreso, since we seem to be sponges for such shit. And given our abilities to see through people to their true motivations, we may have an easier time manipulating others to our aims.
