I didn't want a Darth Vader origin story. Why, Lucas...? Whyyy???
Better yet, make a good one. I never bought into Anikain's heel turn. It was just too easy for him to turn. Sure, Mace Windu was bypassing the whole due process thing was kind of a bummer, but that does not make the following exchange plausable.
Palp: "I want you to go over to that big building, you know, the place where you grew up and made a bunch of friends, and kill everyone."
Vader: "Whaaa?!"
Palp: "When I say everyone, I mean everyone. Including the elderly and kids."
Vader: "You want me to kill a bunch of defenseless kids?"
Palp: "Yes, everyone. Take these clone troopers who are conveniently hanging around with nothing to do with you to make it easier."
Vader: "This seems a bit fishy to me..."
Palp: "Once you have committed the single greatest act of atrocity in the history of the Republic, then we may, just may because I don't know for sure, have enough Dark Side mojo to save your baby-mama from a vague and uncertain fate."
Vader: "Whatever you say boss. I will take your vague and intentionally misleading advice as gospel. What could possibly go wrong!"
Palp: "Muhahahahahaha!"
