(ShB Spoilers) Didn't Hydaelyn, uh...

Technically yes.

But it was basically something wrong vs something wrong.
Sacrifying new lifes form to resurrect all the Ascian pre-Apocalypse would also have been the murder of billions of people.

But the main differences is that it's Zodiark's people that start the war, by proposing the sacrifice of all other life form, those who created Hydaelyn, and the fight between her and Zodiark that resulted is just a reaction to that.
And the Sundering resulted on the creation of new life, when the Rejoining consist on sacrifying the survivor to bring back dead one. In my point of view, we should not bring back what is dead, it's just wrong.


And yes, some of the Dotharl philosophy is correct, but their "extreme" view on it that is wrong, a reincarnated person should have the choice to chose his path, even if it's at the end the same as his previous self (like it seems to be for the WoL), and not impose it on him (the suicid of the little girl is an exemple of how it's wrong). But it seems that the Au'ra have some abilities to see the soul of people, like Ascian, the matriarch of the Mol that can see ours.

In my point of view, we should not bring back what is dead, it's just wrong.

On the other hand, from the Exarch's point of view, isn't that basically exactly he did? In his time, the Warrior of Light was dead, and he chose to sacrifice the people who, to him, were currently alive, to bring us back. And we were happy to support him in that after we found out.
