Honestly, I don’t like the whole “Jedi evaporate when they die” concept to begin with…
Is it to spare the bereaved funeral costs?
Possibly. I mean, I’d be nice of em. That shit ain’t cheap.
Here’s further changes I’d make: When Vader slices Ben, his body’s bisected in gruesome fashion; when Yoda dies, Luke buries him.
I could go with that.
