Sua, what would you have the Jedi do in regards to the Army? By the time Yoda arrived and spoke to the Kaminoans, it must have been obvious to him that this army was ordered for some dark purpose. Should he have just left it there and said, “Whelp, I guess I’ll leave it to be picked up by whoever wants to use it for evil! Bye!” I guess you’d want him to take it and turn it loose, which might be reasonable, but there was that matter of the droid armies being assembled on Geonosis (which Obi-Wan did tell them about) and the potential for danger to a couple hundred Jedi.
It’s a lose-lose situation for the Jedi. Leave the army there, and not only do the Jedi on Geonosis (which included the entire Council) get slaughtered, but the army’s real orderer takes it for evil purposes. Take it with them, and Palpatine, leader of the Republic (and newly blessed with emergency powers) says, “Thanks for picking up that army–I’ll just take it off your hands now.”
Regarding the “fake Jedi” issue, it should have been apparently clear that someone showed up on Kamino using Sifo-Dyas’s name to order the army. Let’s see . . .
–AOTC takes place 10 years after TPM
–Darth Maul was killed at the end of TPM, necessitating recruitment of a new Sith apprentice
–Dooku, who is revealed to be a former Jedi, also turns out to be Lord Tyranus, a Sith. It doesn’t say when he left the Jedi order, but dollars to doughnuts says it was ten years before AOTC.’
–Someone shows up ten years ago on Kamino claiming to be Jedi Master Sifo-Dyas and orders a clone army
–Master Sifo-Dyas was killed about 10 years ago
–The template for the clones, Jango Fett, was “recruited by a man called Tyranus [who we know is Dooku] on one of the moons of Bogden.”
I’m getting a picture here–you don’t suppose that Dooku left the Jedi, joined the Sith, killed Sifo-Dyas and used his name on Kamino to order a clone army, and recruited Jango to be the template for it, do you?
Fenris: So, not only are the Jedi’s powers supposed to be without limit (and BTW, when did Luke ever use his powers to do an MRI or a CAT scan, for crissakes??? If they could do that, Qui-Gon could have just done his own freakin’ midichlorian count–with magic!!!), they are supposed to dump their mission at the drop of a hat?
