This is probably funny in a way I don’t understand, because I miss the reference, and will most likely regret posting this because everyone will learn me now
I'd expect Galadriel to be very much in the "The only good orc is a dead orc" camp. That's based purely on vibes, I don't recall anything about it in the LOTR books and I never could finish The Silmarillion.
But also do Orcs have souls? If they do they should have the potential for good inside them. If not, how are they more than animals? Even JRR wasn't sure.
Tolkien also wrote the orcs as pretty explicitly "always evil", at least in lord of the rings and the hobbit. He seemed to be conflicted about making an always-evil race, but that IS how it's written in those books.
On the other hand Tolkien was quite clear on that the story was told from the perspective of the protagonists. Not least through the strong insinuation that the in-universe book that Bilbo started, Frodo continued, and Sam finished, is if not the book we are reading, at least an important source for it.
Lord of the rings telling them as evil mostly shows that's how the fellowship saw them.
Pretty sure theres a letter or two where he wrote that orcs could be saved, should they turn from evil, but he also didn't know how any of them would ever know to do so.
Wasn't it because they didn't have any Will? Their entire drive to do anything was completely enslaved by whoever was controlling them: as long as they were controlled by an evil willpower they'd also be evil.
Most of today's living elves were already alive back then! By human standards, those times were like the 1990s ... which were actually pretty different times when it comes to political correctness, so fair point actually.
Galadriel had nothing to do with Gondolin but she was definitely in Beleriand at the time. She was around to experience the light of the trees and make her way to Middle Earth with the Noldor.
