You know what? I'm actually fine with this guy sparing the humans. The whole reason he joined this fight was to protect people. Now that he learned that demons are also people, he wants to protect them too.
It's stupid, but also perfectly in-character for him. His reaction to getting betrayed by his student seemed more surprised than angry, though he still hasn't really had a reaction yet. Naive and idealistic perfectly describe him. I fully expect this to end badly for him and everyone he wants to protect.
What I do have a problem with is that he doesn't have any remorse at all for all the demons he had to have killed on the way to the Demon King. Demons that he's just learned were only trying to protect their home. The home that he invaded.

I guess since the demon world is apparently a separate world from the human's, it could
technically be called "isekai" (異 - i - different | 世界 - sekai - world) if you squint.
This completely ignores the fact that the basic premise of every isekai involves someone from Earth or an Earth-like world traveling to some fantasy-esque world.

Honestly, "Man of Valor" is just too awkward even if it's more accurate. A good suggestion in this thread was "Champion" which sounds better.
The problem with translation is that there're times you need to interpret or adapt things to make it easier for the readers to understand while still remaining accurate to the source.
"Hero" is a perfectly acceptable interpretation of "Yuusha" a lot of cases. Using the Dragon
Quest example someone else mentioned, the yuusha is a brave person who saves the world from the evil demon king. Calling him a hero is fine.
Where it falls apart is in cases like this story when there's apparently a whole army yuusha. The word "Hero" represents an ideal of strength, courage, and virtue. The antagonists so far haven't shown any of those idealized qualities. Even if they did, having so many diminishes the meaning of the word. If everyone is special, no one is special.
It's not that no one bothered to fix the mistake. The mistake just never needed fixing before.
You're free to disagree with me. It'd be hypocritical of me to tell you how to feel when I need to hold myself back from hitting something whenever I see kendo referred to as fencing.
