Maybe they could have changed something, maybe not. The Chantry has
immense political influence throughout Thedas and Orlais is its center
of power. It's very important for rulers and nobles to be in good
standing with the Chantry - or at least appear to be. They run many
essential civil services and thus have the power to shut down entire countires, if they wished. They have huge leverage over the mage circles, as well.
They
have plenty of tools, if they wanted to do the right thing instead of
the safe one. However, not only did they not try to oppose the war and
occupation, apparently they outright supported it.
You seem to
have shifted your argument here, from saying that it's all right to
cheerlead war (which will bring rape, pillage and suffering with it)
against Ferelden merely for not being "civilized enough", to saying
that the Chantry was against it, but simply had no power to stop it.
No. You're overestimating it's influence and power.
Kings and generals have more power/influence over their men than the church, yet not even they can stop the rape and killing completely. Name any war in history that happened, and I can name you attrocities commited by either side, regardless of how much effort was put into avoiding them.
And no, I'm not saying war is OK, I'm saying that SOME people may think that.
The Chantry has been responsible for the deaths of mages for over 700 years (the length of time that the Rites have been used).
Yes, they have. And those death was sadly necessary. And lets not forget that the Chantry has ALSO been saving mages for over 700 years and educating them.
And my point is the Chantry took any means of developing medical
treatment for the poor and hurled it out the window placing medicine
and healing at the feet of only the affluent members of society.
They've also taken their most effective weapon against the well armored
and technologically superior Qunari and locked them up in a prettied up
prison.
How so? We see people making healing polutices, that's herbalism. Tehre's also various salves and other stuff, that the Cahtnry doesn't forbid in any way.
Also, kepping your nukes in a safe, contained place? Yes, shocking!
why do you think studying anatomy and corpses wouldn't provide any benefit to medical knowledge?
Given the existance of powerfull healing magic and potions, studying corpses wouldn't have the benefit it has in RL. Also, demons like to posses corpses, so burning them is the default way of dealing with your dead.
Otto seems to have the Leroy Jenkins approach to handeling rage demons.
His death is powered by cutscene power. He seemed quite capable and had his wits about him.
