I think of Chaotic Neutrals as people or beings who are highly anti-social, and who have a general disregard for the value of life - excepting their own, which they value highly.
Who, then, fits that description as I see it?
Well ...
Thomas Covenant, early on in the Chronicles, fits the description.
Daffy Duck and Wile E Coyote, on a more comical note, fit the description.
Conan the Barbarian, as he is depicted in the film, fits the description prior to meeting Subetei the Archer.
John Carter, Warlord of Barsoom, comes close to fitting the description, especially through the first two books of his saga.
Vierna Do'Urden, daughter of Matron Malice, falls just outside the description, prior to the fall of House Do'Urden (chaotic evil with strong neutral tendencies)
Zaknafein Do'Urden, father of Drizzt Do'Urden, falls within the definition (chaotic neutral, bordering on neutral.)
Gollum, from LOTR, could count as Chaotic Neutral, especially during his time with Frodo and Sam.
Al Capone, might have been Chaotic Neutral in Dungeons and Dragons.
Many racist, elitist elves, who believe all non-elves are to be avoided and/or killed, and eschew social life even with their own people, preferring instead to study tomes or strange mysteries, dwelling in libraries or gymnasiums, or wandering alone in the woods, could be considered Chaotic Neutral.
Chaotic Neutrals are just that.
They are difficult people to get along with.
They are difficult to work with, let alone work with in a team effort.
They are not very altruistic or principalled, and some of them aren't very nice.
A Chaotic Neutral Druid might decide it is best if she simply kills all intruders into her forest.
No intruders, no problems for the forest.
A Chaotic Neutral Barbarian may hate mages, and destroy magic on sight, and revel in brawls, battles, and heroic (or half-suicidal) exploits.
A Chaotic Neutral Mage made obsessively brood over his Tomes, deciding he will go on an adventure ONLY after he obtains a certain spell, and refusing to change his mind despite all requests and reason.
A Chaotic Neutral might be very reasonable and amicable, only to suddenly veer off on a strange tangent of thinking and action, typically right in the middle of something important.
A Chaotic Neutral, might simply wish to be left alone, and have gone to great pains to ensure the quietude of it's existence ... and woe to anyone that bothers it (liches are like that.)
Most Chaotic Neutrals will obey the laws, and they will not run around killing people.
Most Chaotic Neutrals are not sociopaths, doing whatever it takes to get what they want, regardless of social norms.
Most Chaotic Neutrals are not hermits, refusing to talk to anyone or dealing with society in any way.
But enough are to make any Chaotic Neutral a dangerous beast.
Most Chaotic Neutrals are simply anti-social, distancing themselves from people and society as much as they can.
They are not sociopaths, but they are not principalled either, and they may well commit unscrupulous or unreasonable acts in order to obtain their desire, whatever it is (whatever it is, may not conform to what most people desire.)
