I just had a revelation about why I love Celebrimbor so much. Well, one of the reasons, anyway.
One idea that’s very prevalent in Tolkien’s work is the concept of hereditary or collective sin. Your ancestor screwed up? You’re probably doomed, or at least have to prove that you aren’t. (See: Aragorn, also movie!Thorin). Your folk did wrong against mine a few millennia ago? Move yourself off my lawn. The doom of Mandos cursed Feanor’s entire house, not just those who swore the oath.
Maybe it’s because I’m German and very much distance myself from the sins of my forefathers, but I have a huge problem with that. Apparently, so does Celebrimbor.
Then he basically says “Fuck the entire First Age, we’re making a new start. Curse, what curse? And remind me again why we dislike the dwarves, they’re pretty awesome from where I stand. Btw, I’m putting the star of my house on these doors, come on, judge me for the family I was born into.”
It’s such a positive attitude and a lot more progressive than most of his contemporaries. Did Tolkien view it as hubris? I don’t know. In any case he knew how to write effective tragedy, because this lack of prejudice may have been a reason why Celebrimbor trusted Annatar, and then… well, we know what happened then.
