[X] You can't be fully sure of Jin Tae's intentions, given his family and work. Keep communication professional and arms length. There is too much to risk here
Renxiang is default skeptical and as unbiased as we can getThe choice is a bit annoying because it'd be useful to have someone more sceptical involved in the planning, who's nonetheless on-board of the main. He would make a pretty good devil's advocate, same as Luo. It'd be a nice way of covering some of our blind spots. At the same time, I don't really care about convicting him we're right.
Well the idea for the first option is that rather than him being a negative influence, we would be influencing him. Its also possible that by keeping him and thus Cao Chun at arms length, we'd be increasing their dislike of our whole idea...Possibly causing them to actively dislike us if it seems like we're keeping secrets from them or going behind their back.In theory we could ally with the MoI here. From the perspective of the welfare of the common people of the empire, Cao Chun and we have a lot in common. Accepting Jin Tae into our confidence would be a big step towards establishing such an alliance.
I don't want that alliance. The MoI want to minimize barbarian and imperial cultural contact by keeping them separate and that seems likely to head into horrifying territory. Keeping an element of distance helps further our cultural project while reducing the influence of what I view as a negative influence.
