A person of neutral alignment can be very different from another person of the same alignment. For example, a Druid might actively defend the center, holding a strong desire that neither good nor evil, order nor discord gain control in the world, for each of them is inherently unbalanced and unnatural. But a Warrior of neutral alignment might be unconcerned about such things and simply wish that all those with such strong opinions keep them to themselves. In either case, the neutral character is not strongly allied with the idea of order or discord, good or evil.
This is a character of an unruly nature. Whether one is in opposition to the tenets of order or just desires to be unconstrained is immaterial. These folks tend to be unmindful of the rules of society, preferring to do what seems correct to them at the moment. This isn't a destructive kind of chaos such as would make a person evil, nor is it a gentle chiding of the rules intended to show where constraints hinder the ability for one to do what is good. Folks of this alignment are most often just unable to understand why others have the right to blanket their lives with rules when those rules can't be accurate for any of the specific situations they find themselves in.
Characters of this alignment believe foremost that sentient races must have rules to abide by, or they will become lost in uncivilized discord. This does not necessarily make them proselytizers of order. It is just as likely that one of this alignment would hold only themselves to such restrictions. Even so, their belief in the ordering of things is strong and they will often find it challenging to allow discord to work around them. One of this alignment will follow the rules of any society he finds himself in, and will tend to avoid the company of those that hold no rules or laws important.
Characters of this alignment believe that being good is more important than being orderly or chaotic. If rules make certain people happy, then they should have such rules. If rules cause others to be troubled, then they should be able to go where such rule do not apply. But neither rules nor a hatred of such rules should be an excuse for a person to be evil. Above all else, being good is what matters. This may only be a personal goal, or it might be something that the character desires for others. In any case, such a person will be unable to abide evil in any form. How they respond to such evil will vary from person to person, but they will never encourage evil and will never aid one that does evil.
Characters of this alignment are uninterested in order or discord. Such disinterest might stem from a lack of concern, or it might spring from disdain. For the most part, a person of this alignment strives primarily to achieve evil ends. Their goals might be personal, or they may wish to impress evil upon others. But evil is in them, and they cannot tolerate goodness. They will never aid a person of goodly demeanor, and depending on their personal desires will either hinder them, shun them, or use them and then discard them.
Characters of this alignment form the heart of many evil societies. Their rules may be cruel, perhaps even frightening, but they are the devices that keep society in line. Evil to the core, these characters understand the power of organization and order, and they know that the way of discord is the way of self-destruction. If you want your dreams to come true, either as a person or a society, then you must have the strength of order to build on. Structure is what makes evil terrible and mighty. Ambitious orderly evils desire the destruction of all that is good, and often have a plan for making that happen.
Characters of this alignment eschew rules as restrictive to the purpose of evil. They believe that confusion and mayhem are they most effective tools available. They find those of order far too constrained by their own rules to be effective. Only those willing to throw off the shackles of order can ever truly be great. Seething chaos is the soil that nourishes true evil. Honor is for fools and Paladins, both of which make fine mulch for the gardens.
Characters of this alignment believe that good is enhanced by order. True peace can only be achieved through the foundation of just rules and true goodness. Discord breeds evil, for those who are unwilling to follow rules most often do so because those rules enforce what is good. Certainly some rules are unjust and should be defied. But such rules are only created by those who are evil at heart. Societies, families, and individuals alike should be willing to do what is right, and to set what is right down as law. Some might be asked to make sacrifices for the good of others. Those unwilling to do so, those who say rules are too constraining and are unwilling to abide by them because it discomforts them to do so, are selfish. Selfishness often leads to evil. Evil is intolerable.
Characters of this alignment believe that being good is an internal measure, not a societal one. Many of the rules that societies create have nothing to do with being good, but are designed to restrict people so that they can't be evil. A fine distinction, to be sure, but how can a rule, written onto a piece of paper or carved into stone by someone days, months, or even years prior have any pertinence to an action taking place right now? Stealing is against the rules in many places, but it is not by its very nature evil. It is only the intent of the person doing the stealing that determines the goodness of the act. Stealing money from an evil man and using that money to feed those who have little is a good act, not an evil one. Rules hinder many acts that are indeed good.
