yoda the great?

isnt yoda supposed to be the greatest jedi ever he has kill many but
loses against plapatine and then gets all depressed like al ittle baby who thinks yoda should of went bak and finished what he sarted in the orignal movies and why in gods name was he depressedt hat he lost

Ok first of if he did go back and finish the job the OT would have been a paradox.
Second he wasn't depressed he was upset he thought he could win Yoda isn't a cry baby.
And finally Yoda didn't leave when he did he risks the chance of being killed and then the Darkside would truly rule the galaxy.
Sry if I sound rude but seriously don't insult Yoda

Wars not make one great.

Yoda is the best, he only went into exile cause he has to wait for when the time is right, which is where Luke comes in

Yoda carries the weight of all the Jedi; he wasn't being a cry-baby, he was feeling the depression of thousands.
