Aurbere has already told you, he didn't want to kill Yoda,
Now you also present this subjective interpretation as being a fact! Nowhere does it say that Sidious didn't want to kill Yoda. Nowhere! It is your interpretation. Please be honest about that.
My interpretation? Not matter how much Sidious would enjoy to torture Yoda, he would never risk Yoda getting away if he had the chance to kill him. Therefore Sidious would strike immediately if he had the chance to kill Yoda.
