That sounds less like helping the person overcome their problem and more like secretly demoting them into a figurehead while the devious Grand Vizier actually steers things.

I don't want my tools to work that way. Especially since the not-so-assistant may be making decisions to favor its parent-corporation.

Once you were in the hands of a Grand Vizier, you were dead. Grand Viziers were always scheming megalomaniacs. It was probably in the job description: "Are you a devious, plotting, unreliable madman? Ah, good, then you can be my most trusted minister.”
