What about this instead:
All persons have an alignment, it is based on what you are doing against people when questing (and in your spare time of course), but you have one more meter, which is called reputation, this measures how known you are, ways to gain reputation is doing heroic things (be they good or bad), slaying a dragon is one thing that gives you reputation, burn a city down is another, the more known you are the better prices you get, if you are evil you get better prices at the merchant cause he does not want to wake up one night knowing he\'s not alone, and the good guy will get a discount cause he is someone you can ask for protection, the neutral is a person you know can do either of them.
Of course a good known (reputated) person can\'t buy fenced goods cause the seller knows he would just use it as evidence, and an evil person might have problems with the authority and would be at a disadvantage in a court, the neutral would have a slight disadvantage of both (but they will be accepted in both worlds).
