This is just a thought... and an unfinished one at that...

But does anybody else think the Empire should refer to the Death Star with a different name? Seems to me that "Death Star" should be a slang term the Rebellion uses to show what a terrible weapon this thing really is. Also, it seems a bit silly for the bad guys to call their battle station something so obviously evil. Wouldn't they be promoting this thing as something that is here for the good of the people while secretly using it to enforce their own agenda? And, if so, wouldn't naming it "The Death Star" kinda blow the lid on that?

Not that the citizens of the universe could really do anything about it at this point, but... I dunno. Guess it just seems a bit on the nose. Might as well name it "The Evil Empire's Big Scary Kill Machine".
