If you are asking about the demons attempted genocide of the elves in the past:
light manga spoilers
No, I don’t remember any additional info about that from the manga.
If you are referring to Frieren’s ongoing attempted genocide of demons:
light manga spoilers
We meet more demons as the story continues and Frieren and co. will confront them. Philosophical discussions about the true nature of demons will be had (are they simply monsters? do they feel emotions?). Those questions might not run through Frieren’s head, but the story does a good job of making the reader ask those questions through other characters.

I was thinking about Frieren. Thank you :3
I don’t really care if Frieren herself thinks about it, I just find it more interesting if the writer has put some thought about it.
