Well, based on the D&D system
? Here's some excerpts from wikipedia about each of them.
Lawful good : "Lawful good is known as the "Saintly" or "Crusader" alignment. A lawful good character typically acts with compassion, and always with honor and a sense of duty. A lawful good nation would consist of a well-organized government that works for the benefit of its citizens. Lawful good characters include righteous knights, paladins, and most dwarves. Lawful good creatures include the noble golden dragons. In the Complete Scoundrel sourcebook, Batman, Dick Tracy and Indiana Jones are cited as examples of lawful good characters."
Neutral Good : "Neutral good is known as the "Benefactor" alignment. A neutral good character is guided by his conscience and typically acts altruistically, without regard for or against Lawful precepts such as rules or tradition. A neutral good character may cooperate with lawful officials but does not feel beholden to them. A doctor that treats soldiers from both sides in a war would be considered neutral good. Examples of neutral good characters include Zorro, and Spider-Man."
Chaotic Good : " Chaotic good is known as the "Beatific," "Rebel," or "Cynic" alignment. A chaotic good character favors change for a greater good, disdains bureaucratic organizations that get in the way of social improvement, and places a high value on personal freedom, not only for oneself, but for others as well. Starbuck from Battlestar Galactica, Malcolm Reynolds from Firefly, and Robin Hood are examples of chaotic good individuals."
Lawful Neutral : "Lawful neutral is called the "Judge" or "Disciplined" alignment. A lawful neutral character typically believes strongly in Lawful concepts such as honor, order, rules and tradition, and often follows a personal code. A lawful neutral society would typically enforce strict laws to maintain social order, and place a high value on traditions and historical precedent. Examples of lawful neutral characters might include a soldier who always follows orders, a judge or enforcer that adheres mercilessly to the word of the law, a disciplined monk, or a cowardly commoner. James Bond, Odysseus, and Sanjuro from Yojimbo are considered by some sources as lawful neutral."
True Neutral : " Neutral alignment, also referred to as True Neutral or Neutral Neutral, is called the "Undecided" or "Nature's" alignment. This alignment represents neutral on both axes, and tends not to feel strongly towards any alignment. A farmer whose primary overriding concern is to feed his family is of this alignment. Most animals, lacking the capacity for moral judgement, are of this alignment. Many thieves and rogues, who play all sides to suit themselves, are also of this alignment. Some neutral characters, rather than feeling undecided, are committed to a balance between the alignments. They may see good, evil, law and chaos as simply prejudices and dangerous extremes. Lara Croft, Lucy Westenra from Dracula and Han Solo in his early Star Wars appearance are neutral."
Chaotic Neutral : "Chaotic neutral is called the "Anarchist" or "Free Spirit" alignment. A character of this alignment is an individualist who follows his or her own heart, and shirks rules and traditions. They typically act out of self-interest, but do not specifically enjoy seeing others suffer. Many adventurers are of this alignment. Captain Jack Sparrow, Al Swearengen from the TV series Deadwood, and Snake Plissken from Escape from New York are verifiably chaotic neutral characters."
Lawful Evil : "Lawful evil is referred to as the "Dominator" or "Diabolic" alignment. Characters of this alignment show a combination of desirable and undesirable traits: while they typically obey their superiors and keep their word (trustworthy), they care nothing for the rights and freedoms of other individuals. Examples of this alignment include tyrants, devils, honorable but undiscriminating mercenary types, and soldiers who follow the chain of command but enjoy killing for its own sake. Boba Fett of Star Wars, and X-Men's Magneto are examples of lawful evil characters."
Neutral Evil : "Neutral evil is called the "Malefactor" alignment. Characters of this alignment are typically selfish and have no qualms about turning on their allies-of-the-moment. They have no compunctions about harming others to get what they want, but neither will they go out of their way to cause carnage or mayhem when they see no direct benefit to it. They abide by laws for only as long as it is convenient to them. An example would be an assassin, who has little regard for formal laws but does not needlessly kill. A villain of this alignment can be more dangerous than either lawful or chaotic evil characters, since he is neither bound by any sort of honor or tradition nor disorganized and pointlessly violent. Complete Scoundrel cites X-Men's Mystique, and Sawyer of the early seasons of Lost as neutral evil characters."
Chaotic Evil : " Chaotic evil is referred to as the "Destroyer" or "Demonic" alignment. Characters of this alignment tend to have little respect for rules, other peoples' lives, or anything but their own selfish desires. They typically only behave themselves out of fear of punishment. They will sometimes even act malliciously for the sole purpose of watching another suffer. Serial killers and monsters of low intelligence are typically Chaotic Evil. According to the Complete Scoundrel sourcebook, Carl Denham from King Kong and Riddick from Pitch Black are chaotic evil. "
