Do we ever see Zhu Jiu try to make anyone's life better? Or even show sympathy to them? He seems to use and discard his fellow Dixingren very easily, and I'd expect that attitude to come through no matter what goal he's working for ...
He's a zealot who wants to be a hero to his people. Converting him (especially baby him) into someone who's out to improve his people's lives on the mass level (legal reform, Treaty renegotiations, etc) would be relatively easy work, even if he wouldn't be the best colleague to anyone.
