Stormtroopers are robots!
Jokes aside, you don’t have to have everything explained to understand something. Yes, they didn’t show the bodies but you with a little use from logic you can see that Leia complaining about her pacific, weaponless planet being blown means it’s not desert. Same goes for the Death Star on which you see there are people until a few seconds later where it blows up. Same goes for everything.
Sure, maybe a kid won’t pick it up but that doesn’t mean Star Wars was light hearted in the OT
So, why is electron a bad idea?
