All I know is that like many of you I was on board with the killing of the traitor to protect our people and as justice for those he had already been responsible for the deaths of. I didn't consider this a "hardening" prospect, it was simply a decision made in war.
I've done -every- single thing to soften her according to every single thread and guide that lists how... and she still killed Sister Natalie and went all Sith on me.
So, one decision early game rendered all that came after worthless. As though the "softening" flag wasn't switched to "on" because of the one convo. Very lame.
So I wonder: What if that guy wasn't the spy, but one of the people in his network was? It would sure make him look guilty, no matter what. So instead of taking the time to find out, even though in actual game play, even if you don't kill him it never comes up again, we just assume he's guilty and kill him, or just condone it by not objecting to it, because despite not having any real authority, we are given the opportunity to speak up, if we choose, one way or the other, that's not a choice that should matter? It's not something that says "Well, the Herald was standing right there, and knew what I was planning and didn't object, so they must approve"? Because to me, if you're listening to your friends plan something that you know is "wrong", and don't speak up, you are agreeing with what they're planning by default, and if they plan something similar later, and you speak up then, they aren't going to look at you like you're a hypocrite?
Regarding the "authority to speak up", none of us have any authority here, and yet we "flood" these forums with our opinions. How is it that it's any different in game? If we think something is a bad idea, and we're given an opportunity to say so, what's really stopping us from doing so? The short answer is "Nothing". Nothing is stopping us from stopping her from just killing that guy, nothing, that is, except ourselves. So if this isn't what we want, or what we expect, why would we condone it, either by agreeing that all traitors should be killed, or by agreeing that all traitors should be killed by just allowing it to happen by staying silent. This decision carries weight, and that's what the BSN wants, until they realize that sometimes, a decision having weight can shoot them in the foot for what they want to happen later. Then, all of a sudden, it's either "We need notes on the choices to show us that we could shoot ourselves in the foot", or "choices that early in the game shouldn't matter".
This choice was perfectly executed, IMO. It sets the tone one wants to have for their Inquisition, and specifically for Leliana. If I want her to be more compassionate, then I have to steer her towards that. If I don't, and she winds up ruthless, it's my fault for not taking the reigns early and steering the Inquisition, and her, in the direction I want. If someone wants to say that being ruthless in dealing with a traitor isn't any indication of ruthlessness, I'll have to question if they understand what ruthless means. Every time this pops back to the first page, however, I'm reminded of the Ruthless Renegade Shepard players that picked all the paragon options in ME 2, then couldn't figure out why they couldn't get a Renegade response when they wanted one.
