I'm going to go with the 9-point alignment system. I'm also going to operate on the belief that "Lawful" and "Chaotic" describe the way of life one favors; Lawful characters want structure and order and discipline, while Chaotic characters want independence and freedom and individuality.
- Good's weakness is its penchant for putting too much faith in its ideals.
- Evil's weakness is its tendency to focus on short-term, selfish gain.
- Law's weakness is its habit of letting rules and traditions blind it to reality.
- Chaos's weakness is its unwillingness to work with or depend on others.
- Neutrality's weakness is its lack of commitment.
Lawful Good: The downfall of Lawful Good is
zealotry. The idealism of the Good alignment, and the Lawful desire for clear rules and principles, mean that Lawful Good characters are prone to become ideologues. Such characters fix their eyes so firmly on the glorious horizon that they never look down to see the innocents being trampled underfoot... or the ground giving way beneath them.
Neutral Good: The downfall of Neutral Good is
despair. With neither the Lawful's trust in a larger cause nor the Chaotic's self-centered streak, Neutral Good characters are most likely to suffer crises of faith when they find themselves inadequate to a challenge or when others fail to live up to their ideals. In such a situation, they are apt to feel that the foundations of their worlds are collapsing; they may conclude that all of their ideals are worthless, and abandon them.
Chaotic Good: The downfall of Chaotic Good is
pride. In this case, the idealism of Good and the independence of Chaos often combine to make Chaotic Good characters think they alone know what is best to do. Moreover, they can become entranced by the romantic image of the lone hero. Unwilling to accede to anyone else's wishes, they would rather stand alone against evil and be defeated than follow another to victory.
Lawful Neutral: The downfall of Lawful Neutral is
rigidity. With neither idealism nor selfishness to moderate their desire for a structured life, Lawful Neutral characters can become fixated on rules and traditions for their own sake. They become narrow-minded, unable to recognize any need for change, and will go down still clinging to laws that long ago lost any meaning.
True Neutral: The downfall of True Neutral is
apathy. True Neutral is the most accommodating of the alignments, tending to adapt itself to any situation rather than making stands on principle. This can lead True Neutral characters to acquiesce in their own slow destruction. With each slight turn for the worse, they shrug and find a way to live with it, and by the time they wake up to the need to make a stand, it is far too late.
Chaotic Neutral: The downfall of Chaotic Neutral is
cowardice. Without Good urging them to help others and improve the world, or Evil driving them to feed their selfish ambitions, Chaotic Neutral characters can seldom bring themselves to stand up to their enemies - it is always so much easier to run away. When there is a danger that can only be answered by standing shoulder to shoulder with others, it is the Chaotic Neutral character who breaks and flees... only to meet death later, alone.
Lawful Evil: The downfall of Lawful Evil is
greed. Lawful Evil characters want the comfort of a well-ordered world with clearly defined rules. Once they feel they have such rules, they set about exploiting them for every scrap of advantage they can get. They become so focused on gaming the system that they forget the rules are not immutable; the system will only stand so much abuse. When their orderly world comes crashing down, they fall with it.
Neutral Evil: The downfall of Neutral Evil is
treachery. Neutral Evil characters do not feel the need to maintain a place in the system, but they also see no point in openly defying it. They use the rules for their benefit, then discard them. As a result, their careers are likely to be filled with abused trusts and betrayed confidences. Eventually they find every hand is turned against them, and every former friend has become a bitter enemy.
Chaotic Evil: The downfall of Chaotic Evil is
weakness. Chaotic Evil characters survive and thrive by strength alone; scorning to subordinate themselves to others, and lacking the goodwill that more benevolent characters earn through their deeds, they rely on demonstrations of raw power to secure their place in the world. The moment that power fails them, their thrones topple and they perish.
