irresponsibility. Those who promote chaotic behavior say that only unfettered personal freedom allows people to express themselves fully and lets society benefit from the potential that its individuals have within them. Someone who is neutral with respect to law and chaos has a normal respect for authority and feels neither a compulsion to follow rules nor a compulsion to rebel. They are honest but can be tempted into lying or deceiving others if it suits them. Good versus evil The conflict of good versus evil is a common motif in D&D and other fantasy fiction. Although player characters can adventure for personal gain rather than from altruistic motives, it is generally assumed that the player characters will be opposed to evil and will tend to fight evil creatures. The third edition D&D rules define "good" and "evil" as follows: Good implies altruism, respect for life, and a concern for the dignity of sentient beings. Good characters make personal sacrifices to help others. Evil implies harming, oppressing, and killing others. Some evil creatures simply have no compassion for others and kill without qualms if doing so is convenient or if it can be set up. Others actively pursue evil, killing for sport or out of duty to some malevolent deity or master. People who are neutral with respect to good and evil have compunctions against killing the innocent but lack the commitment to make sacrifices to protect or help others. Neutral people are committed to others by personal relationships. Within the game, altruistic heroes and creatures such as angels are considered good. Villains and violent criminals are considered evil, as are inherently evil creatures such as demons and most undead. Animals are considered neutral even when they attack innocents, because they act on natural instinct and lack the intelligence to make moral decisions; in the fifth edition, this is expressed by labeling such beasts as "unaligned".

Nevertheless, the rules do allow for individual variances, permitting "a red dragon looking to defect to the side of good"—even though Littmann acknowledges the rarity of such situations. As 5th Edition developed, it removed preassigned alignments to races and monsters. While some monsters have a "strong association to a given alignment", nature is determined by the Dungeon Master.
