I'm not sure there is a such thing as a "noble thief" unless you are INCREDIBLY thorough. The idea of a noble thief falls mainly on the archetype created by Robin Hood, stealing from the rich to give to the poor. In the case of Robin Hood though he stole primarily from the king, though in some cases he also robbed wealthy merchants and what not with no real idea of who they were.
Let's say for example we have a noble thief and a rich merchant prince. The noble thief robs the merchant prince to give back to the people, so we sympathize with the cause of the thief because we exalt his deeds, but more often than not it's because we're given very little information about the person he's robbing.
In this example, what if that merchant prince started out as a street rat, he came up with a good idea and managed to elevate himself above his status (something Ul'dah is known for), or perhaps he's a member of a family that have worked incredibly hard and their wealth is well deserved. Maybe he has a large family and even though he has riches he also works himself to the bone to support said family and give them happiness. These are also very noble qualities, and the noble thief only perpetrates that just because he has something everyone else should have it too. In that example you're only perpetrating the idea that the poor don't need to work or make themselves of use to their society because you'll just rob the people who do work and prove themselves to their community and give it to everyone else.
Noble thief or not, that just makes you and everyone you support freeloaders in my opinion.
