Theory: C3-PO is AI Sith Overlord
I think like Palpatine, C3PO was sort of there too. And Vader made it. And that over time it grew as an AI, got force sensitive, and masterminded it all.
If that fool, jar jar, obnoxious as f***, then why not a space AI android cyborg?
It is plausible.
Happy Star Wars Day!
