Having said that, and the fact that we live in a rigid social order, in an extremely Lawful society. As late as 200-300 years ago, there were people, who lived OUTSIDE society, and their mindset was not Lawful, you'd would type them as Chaotic, but here is the cruxt of it, their culture is largely extinct and you would not know what they were like. Some of it was readily predictable - meet a stranger, kill them, bury the body, take their loot. If you did this to a passing stranger, nobody will ever known. Creepy woodsmen now knows as Economic Serial Killers. Another side - War in Crimea, 1840's, Officer sends his scout to get re-enforcements. In the heat of the battle to his horror he sees the Scout and his men helping out on his flank. It's all over now - they are encircled and doomed. "We saw your boys in trouble and decided to help them!" Yells the Scout when he sees the flabbergasted commander. Historic example of Chaotic Good behavior.
So, here are some character stereotypes displaying real world examples of the nine alignments:
LAWFUL GOOD - Paladin or a Crusader or a Knight Errant, who believes in the system.
LAWFUL NEUTRAL - Samurai Warrior, a Military Professional. These people abdicate from moral judgement and stick to a professional code of ethics when they realize that the system they uphold is corrupt. Alternative is to evolve into Chaotic Good.
LAWFUL EVIL - Weak-side - a member of the gang, a mass movement, or another crowd exercising its will over the others. Strong side - a socially successful sociopath manipulating the system to his or her advantage.
CHAOTIC GOOD - A champion knight living according to Chivalry. Lone Ranger, Davey Crocket, other frontiersmen and vigilantes, who will bend the rules and look the other way for the common good.
CHAOTIC EVIL - A Champion with the biggest fists looking out for number one. A bully. An egotist.
CHAOTIC NEUTRAL - A person dealing with psychosis in out world trying to live a normal life. In fantasy world - a shaman or a witch, who lives partly in the invisible world and has to keep the invisible shadows at bay, lest they swallow her.
NEUTRAL GOOD - An activist or a rebel fighter, who will give up his or her life for the common struggle and greater good. A hero, a fanatic, an individual wholly absorbed by the struggle.
NEUTRAL EVIL - Snowball in Hell, a Blood in a cell full of Crips, a Cop in Prison. Same as Chaotic Evil, but physical survival is an issue in the real world and the person is overwhelmed and sinks morally to stay alive. Any kind of behavior is excused by the necessity, powerlessness, and the need to stay alive. Gold-diggers and prostitutes feathering their nests will fall into this category.
TRUE NEUTRAL - A Monk, an Olympic champion in training, a dedicated artist, anyone so consumed with what they are doing, that they are not part of the world in which the players are adventuring. There is a common interpretation of this alignment - that of Cosmic Balance, and Neutrality and Non-Involvement, but that is typically a position of weakness, of someone, who accepts a bad situation and escape into objectivity to avoid taking a stand and dealing with it. Druids are True Neutrals, as a animals, that's because Druids are too absorbed with the maintenance of their garden and the surrounding nature, the sheer business and amount of work that is required to truly live off the land, that their devotions do not leave them any time to be involved with the world of adventurers.
GOOD vs EVIL. Good is about Altruism and Empathy, which in real world come with age and experience. Good is about love, which means putting The Other above Self. Good can sacrifice itself so that its progeny can live on and thereby it defeats the evil, which can't see past itself and sees its death as the ultimate end, whereas Good dies in the struggle and is reborn. It takes strength and willpower and costs popularity to do good and not go along with the others. Evil grows out of weakness, which often masquarades as preservation of self.
