Not particularly. For example, I definitely see how the Dalish at the time brought it upon themselves. However, forcing the descendants to pay for the crimes of their ancestors is just as bad as what the Dwarves due to the Casteless, and such an act is only ensuring the wounds between the two races will never heal.
Heh i like you; You know that?
Personally? My POV outside of DA? I'd agree the utter destruction of the Dales was most likely done out of spite rather then the tactical importance of said lands or their value in resources. And it also prevented the relations between those races from ever recovering to the extent it was just centuries prior.
But from that aside; It was done and Orlais had every right to do it; Remember Orlais is a conquering Empire that has spread and expanded and created its self as the pinnacle of Human culture in Thedas. It won the war, it got to dictate the terms of the war; I'd say overall? The Dalish got off light enough for me to realize that while they got a raw deal, it was the product of their own actions and something they will ultimately need to address themselves.
It's like i told Lob a while ago; After the war? The Dalish should have sought out Orlais and begged forgiveness, Embraced the victors culture with everything they had within them, Abandoned their dead oaths and served as a functionary of the Empire. There can never be equality if there isn't a common ground and the Dalish must seek to breach that, Why would Humanity? They already won.
