Not sure how you got “because they can learn, they can learn to be good” as the source of the dilemma from the article. It says

In Tolkien’s Christian framework, [being open to morality, like Men] in turn meant they must have souls, so killing them would be wrong without very good reason.

It’s not them thinking and feeling that’s the problem, it’s that Tolkien believed (as a Catholic) that you shouldn’t kill things with souls.

This is a nice contrast to Frieren where demons don’t have souls and don’t seem to be open to morality, either; they understand it in order to manipulate humans but consider themselves outside its framework.

I think I’ve seen this anime.

Sounds like a Bond soundtrack.

I don’t think so (and I say this as a vegetarian), because as you move up the intelligence scale your ethical obligations become more defined. For example, animals practice infanticide, murder, rape, etc etc, and we can’t really expect them not to, or judge them for it. We, on the other hand, should hold ourselves to higher standards. So should the superintelligent alien race.
