To us Emet Selch is evil, but from his pov we are evil. Hell, if more of his people were around they would most likely feel the same about the WoL. We are more or less the giant barrier stopping his people from returning and living once more. On the flip side, we are interrupting his efforts because we don't want to be a sacrifice for a race that is mostly extinct. There is no winning here because Emet Selch and the other Ascians will always feel the need to restore what they lost due to Zodiarc's tempering. I think that is why I sympathize with Emet Selch. It's because if I were in his shoes and I lost everything I held dear I would do anything to get them back. But unlike Emet Selch I would move on and realize that I should instead help the races that replaced my people and let the past go. Emet Selch cannot do that due to his tempering and that is where my sympathies lie.
