This is simply getting ridiculous. You claim now to know so much about Sith psychology that your interpretation of a Sith's act can be claimed to be facts?
Dude, you're the most far out person I've ever met.
And yet, you seem to ignore the facts in favor of your own opinion. Read the novel and watch the movie.
We have seen Sith toy with their opponents several times. Sidious is no different. He did toy with Yoda. The movie and novel show that.
