It isn't an individual's call to judge whether a leader is fit or unfit to be in charge and move against them. Not to carry out orders can be accepted, sometimes (and only in modern times; try to say you were a conscientious objector in the past). If Lambert felt as bad, he should have resigned or asked for a post according to his station. Did he do so? No, he didn't. Instead, abused his position as Lord Seeker to sabotage the Divine.
it isn't? He is the highest ranking authority known with the Seeker Order, add in the fact that he has the authority to dismiss Knight Commanders and assume their Station and I'd say he would be about the person to be able to question the Divine and her orders. It's no diffrent from me then Donitz the Coward Arguing with Hitler, You have people of rank and authority that can push their opinions to the highest echelons of power, and when certain scenario's arise, they can actually achieve command,No more so then she sabotaged the Templars and Seekers ultimately.
When I was mentioning Lambert's betrayal, you said "The betrayal in question that really wasn't a betrayal given the Templar oath is to safeguard mankind from magic, and not to be the private army of the Divine, anyway it didn't even happen so how exactly is proposed action a betrayal in truth?". So then, or you were assuming Lamber was a Templar, or you were saying that the ones betraying were the Templars.
Or i literally meant what i said, The Templar Oath has nothing within it about subservience to the Chantry, And everything to do with being the safeguard against magic, yes the ceremony occurs within a Chantry, but that doesn't negate the fact that they pledge allegiance to the Order and its mission, not the Chantry. And to see their cooperation and history with the Chantry to be so discarded by the Divine? Yes I'd view it as a betrayal and i'd assume so would most Templars.
What did the Divine do? Ah, yes, researching a cure for Tranquility in secret. That's not even illegal, especially with sanction from the Divine. And he gave the order before knowing about what really happened there, so where was his evidence that the Divine was "unfit for command"?
He gave an order. An order is an action. That the order was acarried out or not in the end doesn't matter, because giving the order in itself is treason.
He gave the suggestion to the Knight Captain that under the scenario that results had been achieved, it would be for the best they remain lost,furthermore I'm starting to question if you have even read his reasoning for giving the assignment to Evangeline in the first place. He made it perfectly clear that while the research in his eye likely would possibly be continued under careful templar monitoring if it proved useful, the situation as it sat wouldn't be a good place for its introduction, and magically what do you know? He was right.
The world was too unstable for such a dramatic shift of power from the Templars to the uncertainty of one of their most surefire weapons no longer being effective.
He never gave an order by the way, He never did give a direct command on the issue.
He just prompted that the Knight Captain be aware of the situation, he put too much faith in that failure, it blew up in his face, had he actually given an order? Who knows what would have happened.
