For me, neutral is what would result in any attempt for me to try to play evil. I don't think I would be able to change my general outlook that much.
Someone said that they don't thing there is such thing as good or evil, and someone also said they thought the whole alignment concept was silly (or whatever). On the first point, if there is no good or evil, what is there? Lots of neutral?? You'd make a FINE druid, my friend...they've already convinced you that they are right....
On the second point, I think the alignment system is an EXCELLENT way of evaluating the personality, standards and lifestyle of a character. I have always found myself applying it to real-life people and situations in something of an unconscious manner, because it is a good way to put a tangible feel to a person's behavior. What I have a problem with in the game mechanics is the requirement for a character to CONFORM to his chosen alignment, or ELSE. Or else WHAT? Why cant (a PC, anyway) change his outlook? It should not be regarded so rigidly.
