Any idea of redemption was never stated by me. I stated that banking on Vader whacking the Emperor was the spectral Jedi’s last hope.
Yoda got his ass handed to him by the Emperor in Episode III, and knew damn well that a whiny punk from Tatooine, gold plated Midichlorians or not, was not gonna fare any better.
When Yoda was 860, having taught Jedi Younglings for 800 years, he found himself in the position of being the most capable ass-kicker in the Galaxy (Mace, Ki-Adi, Plo Koon, Qui-Gon, etc. having been wasted). He went nail-to-nail against Sideous with a light saber. It proved to be a tie that was going nowhere.
Sideous then switched to throwing things around, namely 2 ton Senate pods, and Yoda got pwned. Yoda was down 20 ticket seats below general admission after the first volley.
The emperor then lobbed FOUR senate pods at Yoda, whilst cackling maniacally, and the best Yoda could muster in response was to pick up one pod, spin it like a pizza, and send it back in less than 30 minutes.
Then lightning ensued, which Yoda admirably deflected back at Sideous. But he looked like my grandmother after making the daily trip to the mailbox–old and busted, and worn out by the fatigue of the effort.
Once Yoda dropped his light saber (and what Jedi drops his light saber anyway, isn’t that Jedi Code #42065?), he knew he had to run away like a little green pussy and wait for an edge.
No, neither Yoda nor Obi-wan ever expected Luke to take out management throught Force combat. Family heart string tugging, that’s the ticket, that’s the edge. Train the boy to never give in to the Dark Side and to stand proudly before the devil.
“I am a Jedi, like my father before me.”
That’s the ticket.
Make the Chosen One fulfill his destiny.
