I already know how the others companions behave to some decisions and most of them to me are blameless, not because they aren't grey wardens so they are not tied to an oath but for the whole set up of their critical condition which is generated by a morally questionable if not an outright evil warden:
-Sten is one of the few characters that can't leave due to approval status because he always fulfill his oaths as it is to expect from a Qunari
He do not attack the warden with the purpose to kill him/her but with the purpose to see and understand if the leader still retain strength and lucidity
(go on the search of an urn on the top of a mountain during a blight seem to be a little trivial at first and not wise, in fact i dislike that part of the plot because it seem detached from the game) if he win nothing bad happens.
I see that as a good moment in which one of the companions has the strengths to test the protagonist without undermining the quest.
-Shale is committed to help the warden with the sole reason to try to find more insight about herself is kinda like a mutual partnership.
What we know about the character is that she despise slavery since she was forced ino being one by her former master and she was paralyzed for thirty years.
A warden who is willing to kill his friend(in front of her) thus deprive her of a reliable source of information with the sole purpose to promote slavery via the anvil of the void and trust Branka (the same woman who killed them all as baits for the traps) should expect this reaction.
However i will admit that her leaving the warden at camp does not make sense because she couldn't possibly know or remember Caridin.
-In order to force Oghren to start a fight at camp the warden should bash him with several insults since those are the dialogues that trigger the great disapprovals and the fight,so it is clearly an evil warden that wanted that fight in the first place to the point that Oghren will comment that the protagonist is no better than the archdemon and should die along with him.
-Wynne harbor a spirit of faith that saved her while unharden Leliana is very faithful,faith is an important aspect for them both.
A Warden who is unwilling to respect others belief and dessacreate historical relics in front of believers clearly demonstrate a lack of compassion,especially if all of this is done to absolve the task of someone who tried to kill them all like Kolgrim.
Not only their reaction is more than predictable but i do not understand as for why they should not stand against a warden who destroyed a piece of history harbored in sorrow for a thousands of years.
-On Zevran i already said that he can be seen as untrustworthy from the start,even if most of his disapproval are built upon the decision of an evil warden (being willing to kill all the mages and the children,being will to enslave all the elves,or betray the Dalish ecc..)
My point, the bolded is excuse after excuse after excuse finding the others 'blameless' for their actions because , as you put it, "it's in response to 'evil' actions by the warden" or just to "test if the warden retains strength and lucidity"--as if that's any kind of excuse considering the crime he committed to get put in that cage in Lothering. My counterargument was to show how this can all still happen with a warden who isn't evil.
If you're gonna push me into being strict and cynical by using technical oaths and bounds then i can just as easily say that Alistair does not possess the luxury to leave since he is a Warden ,this should end any further discussion you may wish to arise.
I didn't make any excuses for the others companions since there's a whole lot of "if you go out of your way to be an ass, this can happen" in your logic
So you created a lot of scenarios where it's possible for comps to turn/leave, and then point out that they'll turn/leave for some atrocities committed by the warden??
I said nothing of the sort. My examples show how its possible to do it without committing atrocities, without "going out of your way to be an ass". In the case of Zevran and Sten, you are required to do nothing at all to them (except bring Sten to haven). If anything, it's you who's describing a warden going out of his way to be 'evil' causing these things to happen.
I get the feeling we are suffering from a wide, wide gulf of miscommunication here and we are just spinning around in circles getting no where and adding nothing to the debate/conversation.
The only thing I think we can agree on is Alistair's behavior at the Landsmeet is deplorable. Just because I understand it, doesn't mean I condone it, however I don't think it's the entirety of his characterization, either.
And I think it's unfair to characterize any of the companions based on a singular moment in the game that may never turn up. Alistair always leaves in your games because you always recruit Loghain, he doesn't leave in any other instance. Zevran only turns on you if he doesn't trust you. Leliana will turn only if you defile the ashes. Sten only questions your leadership if he doesn't like/know you. These are all 'this condition must be met' situations which don't happen every game or to every player playing the game unless they play the same way every single time. Nor do i believe (or argue even) that this is the entirety of their characterization. They all have more than just that one aspect to their personalities than just that singular moment.
You have your opinion. I disagree with you. Let's just leave it at that and move on, shall we?
