I like Jia Xu. Though he has been portrayed often in a negative light in SGYY, he's still a good adviser and his actions can be understood as from someone with strong morals.
Serving Dong Zhuo doesn't necessarily make him a bad person. Cai Yong, Cao Cao, Wang Yun and many others have worked under Dong Zhuo. If you think about it, Dong controlled the Imperial court at the time. If a person wants to serve the country, then he must be under Dong Zhuo. If I remember correctly from SGYY, he advised Li Jue and Guo Si to regroup to liang province and so on only because Wang Yun rejected their surrender. Can't blame him for wanting to save his own hide (and a number of others).
I don't remember much about Jia Xu except this, his one battle with Cao Cao (in which he totally outsmarts Cao Cao) and his advices to Cao Pi. Cao Pi was the oldest son at the time, and the morals, customs and history of the time indicated that the eldest should succeed the throne. He was simply following his own sense of right and wrong.
Moderation in pursuit of actual work is no vice.
