Sometimes even NPCs have standards. Just because the villain tells them to do something unethical doesn't necessarily mean they'll do it. This can be an interesting chink in the villain's plans for the heroes to exploit. If the henchman might be tempted by appealing to their better nature, it gives the heroes a way to undermine the villain's plans without direct conflict, using a more social or roleplaying approach.
So throw some hints of this out there. Don't have all the villain's flunkies appear to be totally obedient and incorruptible. Make some of them appear a little hesitant, or afraid, or disgusted at what the villain does. Maybe they're just doing this gig to make money to raise their kids, and they have other things on their mind than carrying out the evil dude's every whim.
Commentary by memnarch (who has not seen the movie)
That's a very interesting NPC discussion there. I wonder if it's somewhat close to the movie dialog or if it's just the GM sprinkling hints of NPC backstory in for the fun of it. And if they're meant to be characters we've heard about before. I imagine that we'll find out more later when we get to the comic(s) with Jim in the kitchen. Or at least whatever the GM can filter in around Jim's unique perspective.
Until then though, let's just enjoy C-3P0's brain extraction and the dangerous fun that will come with it and its results. Not that Threepio has a brain.
