The way I see it, it's about how much control Keith has over a reviewed body; Silver was not completely free to act. When I saw this scene first in the manga, I read his "plan" (too generous a word, I agree on that one >_<) as a futile and tragic struggle against Keith's will. The way I understand it, his alligance was bound to Tartaros, he was bound to fight Gray and he did not have the freedom to do any of the things Carry listed. He had nothing, just his consciousness observing, and he could do nothing, just to use his words.

From this viewpoint, his actions make kinda sense to me. Note that I say "actions", not "plan", because as far as plans go, I think he had none, he acted mostly on impulse. Just imagine this; you have no freedom to act, then suddenly you are pitted against the last surviving member of your family, your own son. You can only chose what you say to him. Do you tell him that you're his father? Hell, no. You make him as angry as he can be, you make him want to fight and kill you, because that is your only way to maximise his chances of survival against you. I say it is a good situation, and the only way I condemn Mashima for it is that he did not go deeper into this interesting stuff. :)

Of course, it's still convenient and slightly illogical writing that allows the writer to pull any bullshit ("things happened this way, because Keith's control over Silver was exactly so strong that things could happen this way" - sounds fishy >_< ), so yeah, there's that. But as long as its entertaining bullshit like this, I'm game. :)
