Partial credit for that bit about Vader. In Return of the Jedi, Luke surrendered to the Empire on Endor to get close to Vader so he could try and talk Vader into redemption - that's how Luke ended up on the second Death Star where he later cut off Vader's hand.
Now what about;
*The Wicked Witch of the West (who spawned the book/play/movie/franchise "Wicked").
* Dracula, who had at least 2 movies whitewashing him (the 1992 movie and the 2014 movie)
* Loki (anything from Marvel in the last 10 years)
* Magneto (also Marvel, but for even longer than Loki)
* Stalin (when was the last time he was a villain in fiction?)
* The literal devil (the series' "Lucifer" and "Hazbin Hotel" to name two).
There's more, but if there are people will whitewash the literal devil himself, who won't they whitewash?
And yet Zambia - a nation with Christianity as the state religion, is a safe country. Unlike Pakistan (Islam is their state religion) or China (which espouses State Atheism).
