@Tzeentchian Apostrophe: You think Uldred would have "thought about the children"?
And Kirkwall is an anomaly - they've said this many times.
Do you really think this mage rebellion is thinking about children anywhere? The children getting bombed by random fireballs? Shot by random arrows? The mage children being consumed by demons because they're so full of fear and fatigue during a time when demons are literally raining from the sky?
Yeah - not a single group is "thinking about the children" in the current scenario.
And don't even get me started on anyone who did the Dark Ritual saying something like this.
Of course not, this is why Uldred is the villain in this story, funny that it is someone like you who sees the similarity between Uldred's ideas and carelessness to the Templar's doctrine.
Kirkwall is an anomaly when someone brings it as an example to Templar cruelty, but a servicable example for how mages are bad and should be treated even worse, right?
I doubt that mages go around burning children even during the rebelion, sure, I can see a innocents getting hurt if Templars jumped a mage in the middle of a street, but that's something else entirely, there is a clear difference between victims of collateral damage to thrusting a sword in the heart of a child that did nothing wrong.
Morrigan's ritual has nothing to do with this, both because what was born was not really a child but rather a very different being, and also because there was no harm caused by it to anyone living. The morality of this also depends on wether or not you believe Morrigan's explanation (which I have no doubt that you don't...), because personally, I don't think morrigan (or rather Flemeth) hoped to take the power of a god to herself, but rather bring into the picture a counter to the power of the Chantry.
Of course, this whole deal may rankle a religious person sensitivities, "playing god" and all that, (and maybe also the abortion thing if you believe that there was a living fetus that got killed by the ritual) but that's rather subjective.
