IGN - Companions, Solas and Varric -

So glad they showed we can give back as good as we get from him, even if I don't think they do show his response. Honestly, he had multiple opportunities to say to his former colleagues that he wasn't trying to destroy the world and we weren't all going to die as a consequence of his plans. Why did he say what he did to the Inquisitor in Trespasser? Why didn't he correct Charter in Tevinter Nights? When he said the elves that remain may find the end result better than before, she took that to mean her human lover wouldn't survive. The reader also understood it that way. Then Varric is pleading with him and his only response is people die all the time.

Is it possible he is doing his damned equivocation again? No, he wasn't destroying the world but healing it. The fact that the healing process would kill countless millions of people doesn't take away from the fact that when it is over the world will be a better place. I suppose an appropriate analogy would be a cancer treatment. It kills the corrupted cells but also a fair few others as well in the process, although eventually the body as a whole will survive.   So he wasn't destroying the world.
