I agree totally with this thread. Though, I think people are overlooking something important. Obito is a master of psychological warfare, which he has demonstrated numerous times. Taking advantage of Kakashi's well-known issues regarding his and Rin's deaths to throw him off balance is perfectly in character.
So assuming that his motivation is as simple as that is really short-sighted.
