Target: Death Star

I've been mulling over a seemingly recurring Star Wars topic for a little while now, and I think I've got my thoughts together enough to make a post about it, for all that I'm slightly worried I'm taking on something too big for me, to result in annoyed responses or just an ambiguous silence... In any case, though, the topic that I've noticed is that every so often, when the discussion turns to "good and evil" and all that, someone will toss out "Yeah, well, Luke blew up the Death Star!", and it seems to me that this is meant to cut the ground out from under him and the "good guys" almost as a whole.
( Contemplations ensue... )
