NG and CG thieves are very possible. NG characters believe in helping others and doing good deeds, but they steal from anyone who doesn't need their money and don't care about the law. CG characters would likely hate the law and cheer when the law is foiled, because even if it's good, it's still interference with people's freedom.

IMO, Neutral Good is the mostly purely good alignment. Lawful Good characters bother about politics and rules which sometimes interfere with what is right. Chaotic Good characters do the same, although in a different way--they are always trying to bring down civilization, except when it's good, in which case they grudgingly tolerate it. Neutral Good characters, however, have no restrictions--all they care about is what is right, law be blessed or law be condemned. Nothing gets in the way of their good.
