The "gold kobold" thinks of himself as a little gold dragon, which among other things means he thinks he's Lawful Good. This probably isn't true but he acts enough like it that he's probably separated from the normal tribe either as an outcast or a splinter leader. Because he thinks of himself as a "good guy", he will display most of the stubborn, "lawful stupid" aspects attributed to paladins. Other than that, he's a pretty typical kobold... he probably doesn't know what Lawful Good is and would have trouble accepting the PC's definition of it if presented with it.
In my group, he'd probably end up as just another kobold corpse like all the others, with all that background material meaning nothing at all!
