That is true, but Tolkien himself said many times he was very troubled with the fact he wrote a “pure bad” race and struggled to find a balance. He said he wanted to include a good orc to help Frodo and Sam in RoTK but due to pacing issues he had to cut. In the books Faramir says that he somewhat feels sympathy for them, having their own families and just being indoctrinated by Sauron. I feel like there should be a balance between the movies “evil pure bad kill everything” and the RoPs “I’m just a wholesome family man trying to feed my kids”
