The only good work done in Star Wars is the stuff that tries to question the binary of the setting. KOTOR II, Shatterpoint, Traitor.
So the other Zahn books don't count?
Allegiance,
Spectre of the Past/
Vision of the Future?
Don't try to sell me on these as examining shades of gray vis-a-vis the Force, because they don't. They do plenty of examinations of shades of gray, but they set out the case that for a Jedi things are black or white very strongly as well. Different standards for those with different abilities. Other books would suggest that the same standards apply to all regardless of differing abilities.
It's a useful and valid literary tool is what I am saying and it is one most people are familiar with and can help the reader/viewer/gamer feel empathy for the situation.
That's just blathering. It's only useful and valid if the setting allows for it. And the setting does not.
Shades of gray would be what finally brings peace to the Star Wars galaxy. The Good vs Evil thing has only led to a constant seesaw between tight wad Jedi, to uppity and stupid to keep the Sith and check and ham fisted Sith to busy being evil jackasses to hold onto power once they've got it. Whole galaxy is constantly embroiled in war over because neither side can rule properly.
I hate to point it out, but you're not seeing the forest for the trees. Like the ten thousand years of the Old Republic or the period after
Vision of the Future but before the Vong came along. Working long-term systems
have existed, and your point is without evidence.
Seriously if ever a group of realpolitik force users came around, it'd be the best thing for the Galaxy far far away.
Force don't work that way.
