A really early one, wherein he physically abuses at least one pregnant woman.
Okay, just Wiki-ed it. I obviously can't read it today, but it says he "loses patience and slaps her" while interrogating her and then leaves. While not a good move, obviously, simply referring to it as "abuses a pregnant mage" is deceptive, I think. I'd have to read it to be sure, of course. I mean, I can remember times my mother lost patience with me and slapped me as a kid (once or twice) and I never considered that ABUSE. Certainly not good - though I actually would goad her because it would mean I'd get no other punishment since she'd feel badly - but not abuse.
Well, it's certainly not Irving or any of the others in Uldred's room, as Uldred kept trying to forcibly possess them.
How would Gregoir know this? From where he is, waiting for Annulment?
Why would they be exiting the Circle tower, then? And where would they have come from to begin with? It isn't as though Ferelden has multiple Circles. Also, your claim that corpses must match representation of living people strikes me as extremely arbitrary.
In short, actual proof that the Annulment would have killed more people is utterly nil and contradicted by the one cutscene that covers it.
Why does my claim that corpses matter arbitrary? You are using one cutscene, many months later, as proof that those people were all in the Circle to begin with, when we know that Enchanters leave on Circle business (and that anyone fighting must be an Enchanter, not an Apprentice) all the time. We see only a few mages alive during or after (if you return), not 100. We see more bodies than mages or templars alive inside. Why is the ratio irrelevant? Because it doesn't fit the narrative you wish to create?
I agree that proof the annulment would have killed more people is nil. It seems fairly clear most of the Tower was lost/dead already. I don't think you said what you meant to say though.
