Because there is no reason why this should be a consequence of our action, and why there should not be a way to change course until after a certain point. The consequence does not follow logically (or even plausibly) from the action.
The game offers a lot of freedom and opportunities to do unintended stuff. Like how they thought about what to do if we slaughter everyone in the caravan in the prologue. Until now, I've found out three different ways for Calisca to die (plus getting her killed in combat or doing that myself), and there's probably more.
The contrast to this quest line is so jarring. It's not a choice and then a consequence, it's the game preventing us from completely logical actions. Like making amends with the Crucible Knights by demonstrating that we're most definitely not
in league with the Dozens. Shouldn't that be possible?
Staying with that example: Wenan (not only a member of the Dozens but also the one who runs an expedition kickstarter) recruits us for an expedition. The Knights might not like that - but my character screen tells me that my standing with the Knights is "Good" or "Hero" or whatever (can check later). At that point, I was simply "Moderate" with the Dozens, i.e. I had better relations with the Knights. It stays the same after accepting and even finishing the quest! Why should I prefer one information over the other? And how should I know which one the game expects me to believe?
We get to the other party and they tell us that Knights guard the entrance to Lle a Rhemen. We proceed to kill them (the party, not the Knights).
If we return at that point, we are chums with the Knights, killed some Dozens, prevented their expedition, in fact: everything went just great for the Knights.
Why exactly is that a reason for the Knights to believe that we're not on their side? That doesn't compute.
It's not that consequences should always be spelt out.
It's that this particular consequence does not in any way follow from our actions - and if that happens, it would be nice to give a hint. "Dear player, we know it doesn't make any sense, but please be informed that if you do X, Y will happen."
