True, but Yoda here probably has only one chance of getting a Sith because then there would be a bounty on him throughout the galaxy afterwards and Yoda would probably go into exile.
Pfft. Yeah, like Yoda needs to worry about bounties. Eliminating Darth Sidious would have made the newfound Empire fractured at worst, back to normal Republic at best. Yoda would not be apprehended in time to prevent him from flying to Mustafar to WTFpwn Anakin.
I believe if Yoda had one chance to surprise a Sith, he would go after Vader. Sidious's weapon to eliminate the Jedi and cause an iron fist throughout the universe is Vader.
Except that Vader's coup has already taken place, and again Vader is the lesser of two evils, as indicated by the fact that Yoda sent Obi-Wan to deal with him, while he took on the Sith Lord Sidious himself.
True, Vader may not be a great leader. Still read below.
Nor would he be a legitimate leader. I doubt that the Empire would be consolidated under Anakin Skywalker, former Jedi, after the untimely death of the Emperor, while Yoda still lived.
In addition, Yoda knows Sidious > Vader and that Palpatine would most definately be his equal. Yoda has enough knowledge to know he's going against a powerful Sith Lord, one who has eliminated the Order's best, turned the greatest potential knight, and who has masked his prescence for decades.
Yet these feats do not deter him.
Yoda knows that there is a chance that he can fail against Sidious.
But he also knows that only he can withstand Sidious since Mace is gone.
However, he knows if he gets rid of Vader, he can prevent the galaxy from seeing the most powerful Sith from ever occuring (this is before the Mustafar duel, so Anakin still has potential).
Nonsense. Yoda was never cowed by Anakin's potential, and he certainly had faith in Anakin's immaturity and foolishness in the canon story. I don't see any rational reason why this would change if Obi-Wan were replaced by Ki.
If Yoda fails against Sidious, then he knows he won't another opportunity to surprise the Sith again, as there would be bounties on him throughout the galaxy.
This is true.
Nevertheless, I see where you're going at Janus.
Of course.
