I can't not vote for C for that first one, despite the fact that it might fail spectacularly (either now, or somewhere down the line should anyone else find out that the Emperor is there). It's too Jing to pass up. And really, even if we die during the attempt, "died trying to kidnap the Emperor and fool the entire country into thinking he became immortal and ascended to heaven while actually keeping him imprisoned on a deadly island ruled by a murderous psychopath" is a pretty legendary way to go out. Jing would be remembered by history as a horrible, horrible villain, but hey, it's not trying to take on an entire bandit city with six guys and being ignobly killed without anyone remembering our name. I'd be satisfied with that. I'll keep B around as a contingency vote should C somehow have no change of winning, though.
The other two votes are tougher. For the second vote, A would allow for the "keep horrible deadly animals behind jing's eyepatch" plan people have been pushing for, and B seems really useful for a lot of different things. Improving offense, improving defense, disabling enemies without killing them... hell, we could take to wrapping people up and hanging them from things Spiderman-style if Jing thinks it's amusing enough. C would probably help make sure that this plan actually works, and even more Agility is always a good thing, but it's been mentioned we can get it later.
For now I think I'll go with 2B just for the sheer versatility of things we can do using that technique, even if "secret poison animal eyeball attack" is great. Better yet, B isn't even horribly unorthodox and dishonorable the way A is, which is useful if we ever want any of the orthodox sects to respect us.
For the third vote, given our recent eye injury we may very well need that Reikan upgrade, but then again even more stealth is good (especially for what we're about to try to attempt), and we tend to pick stealthy options more often than not.
