I really did like Torinaga as a character and bookend comparison to himself as an apex bird of pray.
In the first episode he says he's the bird that stays close to the sun and attacks you when you least expect it, and here in the finale he's sort of mocking the idea he controls the wind, he just observes it's currents like how birds navigate the air currents.
His scheming ability is just judging how people will act and using it to his advantage. Ok Mariko wants to die, when is that going to work best for my plans. My idiot failson is probably going to get himself killed, when is that going to work best for my plans. Yabushige is a textbook disloyal vassal who is going to try and side with the perceived stronger party, when is that going to work best for my plans.
John trying to goad him at the end saying "I used you, I fed you shit" is like the ultimate way to endear him to Torinaga cause he's like duh obviously that's why I used you back, to much greater effect. You were the perfect diversion for everything I did, you were gonna run around Japan like a maniac no matter what so I might as well make it work for me.
Contrast this with Ishido whose management style seems to be screaming that everyone has to vote the way he wants and ignoring what they want to do. I'm just going to ignore the wind and try and fly against it.
