Neutral Evil
A Neutral Evil character is typically selfish and has no qualms about turning on its allies-of-the-moment, and usually makes allies primarily to further its own goals. A Neutral Evil has no compunctions about harming others to get what it wants, but neither will it go out of its way to cause carnage or mayhem when it sees no direct benefit for itself. Such a character abides by laws for only as long as it is convenient. A villain of this alignment can be more dangerous than either Lawful or Chaotic Evil characters, since he or she is neither bound by any sort of honor or tradition nor disorganized and pointlessly violent.
Another valid interpretation of Neutral Evil holds up evil as an ideal, doing evil for evil's sake and trying to spread its influence.
Examples are an assassin who has little regard for formal laws but does not needlessly kill, a henchman who plots behind his or her superior's back, or a mercenary who switches sides if made a better offer. An example of the second type of Neutral Evil would be a masked killer who strikes only for the sake of causing fear and distrust in the community.
