I hate Lord Sidious so much! Here is my story about what should have happened. Windu shouldn't have died either. So, here it is. Enjoy! This takes place in The Revenge of the Sith at the battle in the tower, where Anakin becomes Darth Vader.
Windu held his glowing purple saber to the Sith Lord's neck. Just because Anakin said that he needed him, did not mean the Sith Lord was going to be saved. In fact, he wasn't.
"AGGGGH" screamed the Sith Lord as Windu thrust the saber through his body. It trembled once then lay still.
"What have you done?" yelled Anakin. "I needed him to save Padme."
"He was just feeding you lies, to get you to come over to the Dark Side," Windu replied. "You see his body? That is his hideous twisted soul. That is what you would have become had he 'helped' you."
Anakin stared at the twisted body.
"I didn't want his help, I just can't have Padme die. I love her too much." Windu stared at the Jedi.
"It does not matter what would have become, just what is now. Come." Anakin stumbled out of the room, not even sparing a glance at the sick, twisted, evil body that had contained Chancellor Palpitane, who's real name was Darth Sidious.
Windu turned to look at Anakin. "Due to your honesty and truth, you have earned my trust and the right to become a Jedi Master. Welcome to the Council, Master Anakin." Anakin was filled with joy. The Sith Lord was defeated, he was Jedi Master and Padme was going to be safe. He was never again to be tempted by the Dark Side. He was safe.
HA HA HA! I have successfully ended the series here, Darth Vader is non-existent and Lord Sidious died an extremely pitiful and horrible death. HOORAY! Read and Review, por favor.
