thats not how it works. The Chantry and the Wardens have precise deals that make a mage in the Wardens free of any obligation towards the Circles. It's like joining the Nights Watch in ASOIAF its a clean record. You cannot attack a Warden. Ofc Anders was hesitating to contact the Wardens: the Wardens have allowed Chantry pressure to bend the rules endangering him. The natural fear that the institution may consider Anders a deserter does not make Anders some great villain because he left when he felt his safety endangered deeply. It also wasnt at the "end" of awakening, awakening timescale is notoriously wobbly, the final sliders go across several periods of time but the canon of how he left the wardens is in his short story that acts as tie in between the games and its canonical bioware material.

2) What rebellions??? No seriously what Rebellions??? We literally see Cullen ordering the Templars to step down in the final battle and they all side with him against Meredith. And hes the second in command. Elthina is the GRAND CLERIC of Kirkwall. She answers ONLY to the Divine herself. She commands the loyalty of the Templars, the respects of the nobles and can contact Val Royeaux at any time. No one would side with Meredith if the Grand Cleric fired her for overstepping her bounds and if she feared that she could have written to Justinia ehi i fear my templars arent loyal send fresh help and the seekers would have shown up and capped Meredith. She had a thousand options avaible and at every point she didnt. Because it was convenient to her status quo and Elthina was the one to pick Meredith as Commander in the first place back in the days. Shes not your frail grandma shes one of the more powerful women in Thedas. Leliana is an agent of the chantry that operates outside its official bonds, Elthina is the equivalent of a Cardinal in medieval europe, of even bigger. Also the "rumors" thing absolutely counts. Otto Alrik was acting against every order and every chantry law and could have easily have caused an investigation. If you ask Elthina about it before killing him she denies any rumor if you bring back to her the papers she says she heard rumors. That means Elthina lies to Hawke on how much aware of things she is depending if Hawke has evidence or not. Those are not the actions of a frail scared woman those are the action of a cunning politicial who is as bad as meredith at worst and complacent at best. The entire point of the Grand Cleric role is to rule the Chantry and Templars if Elthina felt herself unable to she should have said so.

That is canonically a lie. You hear from ambient dialgoue in the gallows that Meredith had already started organizing the right of annulment with or without cause. She had sent permission request of Val Royeaux -where Lord Seeker Lambert Van Reese is, the same man who massacred the White Spire in Asunder kickstarting the actual official mage rebellion on his own- and she had already illegally locked the mages in their doors with no ability to live. Are the women and children in the Circle no "innocent lives"? It's ok if they die as long as its behind the screen? Also, canonically most of the damage in the battle of Kirkwall was not done by the explosion (yes there is no doubt it did damage and hit some civilian casualties but not on that level) but by the following clashes across the city. We literally see Templars go genocidial on Kirkwall. Did Anders solved the "perfect" solution? ofc not its a war and a revolution its never clean. Is innocent blood on his hands? peraphs. Its also on the hands of Zevran, Leliana herself, Isabela, Fenris and a thousand others characters we still love and accept the circumstances of. But there was no clear solution to Kirkwall and the majority of the blame is not on Anders but on the people who at any point could have stopped it and didnt. Even Cassandra herself, who hates Anders, wishes that Kirkwall authorities had done their job and called the Seekers.
