Bleed the Man
Arcane
I'm sorry, but your claim just falls apart from the moment that for Thaos plan to work is imperative that animancy gets blamed. It's all that matters, all he's done is with that purpose in mind. You don't leave the decision that will make your plan succeed or fail in the hands of other than yourself.
I mean, blaiming animancy is the cause that hundreds of children are born without soul. You don't go to such extremes and leave this kind of decisions to fate.
Why not actually deal with my points instead of repeating your position after I refuted it as if it answers the arguments:
"Third, he is not personally at the asylum when you meet him there, implying he can keep control over bodies from a long distance. If he was planning to assassinate the Duc he should already be in the animancer's body. Instead he shows up personally and risks exposure because he was never planning on it and thus did not get the chance to hijack the body before the hearing."
This stands even if I grant that Thaos had to do it himself.
To make matters worse he's just chilling in the Asylum until you chase him out. No urgency whatsoever even though the Duc could make a pronouncement any moment. It's obvious that nigga had no plan to kill the Duc until you forced his hand.
But even if I granted this third point, which I could do (Thaos showing up is to make clear to the player that he's responsible of this actions), that wouldn't make your position that the duc's assassination is a bandaid stronger, it just would mean that the execution of this segment could be done better. The key of my argument is that the entire motivation for Thaos character is the outcome of that hearing. If you can't refute that with more than "the duc is a reasonable man that would ban animancy" I can't think that you're right.
