We're a self-centered race constantly striving for approval and acceptance of others but everything we provide others is essentially a monkey paw'd version of what they actual want/need so our race became reviled and ostracized. So instead of turning over a new leaf and actually rebuilding our reputation by refining our understanding of the various knowledge collected by our race we doubled down, started cursing/killing/sacrificing other races to a Demon King we thought was reviving(lol @ them) and now that we've finally angered someone with the power to not only fight back but to essentially slaughter us wholesale we're getting our just desserts(But it's so unfair! Why were we persecuted and reviled!). There genuinely hasn't been one redeemable Posehai in the entire story, and I'd be surprised if there was a single person who has interacted with one, disguised or not who would mourn them either.
