This question actually comes from an EckhartsLadder video I watched some time back, can't remember which one, but it was about Star Wars and the Clone Wars.
As the question suggests, did Dooku know that the Confederacy of Independent Systems (CIS) was ultimately set up to fail and lose the Clone Wars? I mean, the Clone Wars were ultimately caused by Sidious to uproot and overthrow the Republic, as well as the Jedi, and instate a new order.
But did Dooku know this in the grand scheme of things, considering that he was the "face" of the CIS or was he kept in the dark about Sidious's master plan?
