To me, the notion that a CN would care what happens to people outside his own personal circle of friends is flawed. A CN might care if you hurt someone he loves, but, hurt some stranger? Not my problem. Can you imagine Jayne, from Firefly, or Q from Star Trek TNG, giving the slightest toss if some stranger gets hurt or killed? Let alone taking an oath to righteously enact vengeance upon the perpetrator?
I certainly can't.
My best summary would be
Good = generally tries to help others
Evil = generally trying to harm others
Neutral = generally being indifferent about others
Law = generally follows the law
Chaos = generally doesn't follow the law
Neutral = generally indifferent about the law
I would classify Q from Star Trek as lawful neutral. Jayne from firefly I would classify as Chaotic Neutral.
A vengeance Paladin's alignment is really going to depend on the campaign he's in. He can be put in situations where he would nearly always follow the law. Where he would nearly always break the law. Where he would nearly always be viewed as good or nearly always be viewed as evil. True neutral might be the best general classification for him and that would tend to shift for him in any campaign to any alignment.
