*I was waiting to be the first on the page* I'm always Lawful Evil on those quizzes. *Quiz* Hmmph. Lawful Neutral. It's LE when I take it from the perspective of living in the D&D world though, I.e. being an adventurer. In general, I'm closer to Lawful Neutral in terms of what I actually believe, but I have a fondness for Lawful Evil. I'm just all over the Lawful axis though depending on the moment, so Lawful Neutral is probably correct.
A lawful neutral character acts as law, tradition, or a personal code directs her. Order and organization are paramount to her. She may believe in personal order and live by a code or standard, or she may believe in order for all and favor a strong, organized government. The common phrase for lawful neutral is "true lawful." Lawful neutral is the best alignment you can be because it means you are reliable and honorable without being a zealot.
Lawful Evil- A lawful evil villain methodically takes what he wants within the limits of his code of conduct without regard for whom it hurts. He cares about tradition, loyalty, and order but not about freedom, dignity, or life. He plays by the rules but without mercy or compassion. He is comfortable in a hierarchy and would like to rule, but is willing to serve. He condemns others not according to their actions but according to race, religion, homeland, or social rank. He is loath to break laws or promises. This reluctance comes partly from his nature and partly because he depends on order to protect himself from those who oppose him on moral grounds. Some lawful evil villains have particular taboos, such as not killing in cold blood (but having underlings do it) or not letting children come to harm (if it can be helped). They imagine that these compunctions put them above unprincipled villains. Some lawful evil people and creatures commit themselves to evil with a zeal like that of a crusader committed to good. Beyond being willing to hurt others for their own ends, they take pleasure in spreading evil as an end unto itself. They may also see doing evil as part of a duty to an evil deity or master. Lawful evil is sometimes called diabolical, because devils are the epitome of lawful evil. Lawful evil is the best alignment you can be because it combines honor and dedicated self-interest. However, lawful evil can be a dangerous alignment because it represents methodical, intentional, and frequently successful evil.
I recommend
this site. It has the same quiz, but with a breakdown, and a lot more information of the alignments themselves. It also has
this, which makes a character based on your answers. I've got work to do before I go to sleep, so I'll post my results tomorrow.
