We're talking about someone who was raised in an occupied territory and was given a full education from the Garlaens and based on the echo flashback seems to have embraced their view on the world entirely. Having been rescued by Zeno (even though based on Zeno's voice tone it seemed entirely coincidental). He seems to developed a certain level of belief in Zeno's power and his some aspect of his perspective given his statement about his radiance being greater then our own. The WoL did defeat Zenos completely (as far as the WoL is currently aware). So unlike a lot of enemies that we've had Asahi vendetta seems to be specifically aimed at the WoL. What this means for the actual situation and how much was true and how much was bullshit is kind of 'wait and see'.
