Unless you want to shrug off the onscreen destruction of Alderaan, you can't possibly ignore the fact that Star Wars has tragedy out the ass, and I'm not talking about Jar Jar. You can't even make the accusation that its ethics are black and white, in light of the prequels and especially the expanded universe. The ethics of Star Wars are even more convoluted and controversial than our own.

Alien ghosts can come to Earth the same way I can get across town; calling a taxi. The difference is that their taxi's a giant goddamn space rock and mine's a Ford Pinto with bullet holes in the trunk.
