No. Hate to brake it to you. Your word is not law. The fact that you have "said something before" does no make it so.
Sidious wanting to make Yoda suffer instead of killing him immediately if he could, is your interpretation. As I've said before.
No. My word is not law. But G-CANON is. And G-Canon states that Yoda was no match for Sidious and that Sidious was toying with him. Seriously just watch the movie and read the novel.
