OK, this bothers me. Let me try to explain.
Let’s say the empire is building a big bad thing in a museum. The easiest and most effective way to get rid of the thing is to just nuke the shit out of the museum. However, there are thousands of years of history, blah blah. There is a way that it is POSSIBLE to lure the troops out and disable or destroy the thing without destroying the museum.
Now, as you can imagine, the dark side choice is to nuke the museum to pieces while the light side choice is to disable the thing while still preserving history.
But this is a bullshit choice! The light side option doesn’t actually carry the risk of failure, despite what the NPC’s say. The reason that you would nuke from orbit is that you aren’t sure that you can do it the stealthy way, and people’s lives are on the line. There is no chance in this scenario that the light side choice will fail and the empire will be successful in building or using its thing. You can safely pick the light side choice knowing that the people will be safe and sound even if you take this in-theory risky method.
Would it even be a light side choice if you could fail, leading to the demise of innocent people? Of course not. But the way it’s presented, you can absolutely do both successfully: save the people, save the history. If it’s a choice between people OR history, history becomes a dark side choice. But if there is a WAY to save both, it’s assumed that you CAN save both. And that is a faulty assumption.
