Two things, anon.
Firstly, as my post says, this is Wesley!Verse headcanon. My verse is intended, expressly and explicitly, to reinterpret and examine canon in order to make a new statement. So in that regard, I don’t really care what is made “clear” by the published Silm. Being The Most Canonical was not and has never been one of my goals as a participant in this fandom. If you prefer a verse in which everything Melkor makes is 100% evil and has no motivation other than “because evil” and therefore QED evilevilweevilsteevle, then there are plenty of other interpretations out there for you that are not mine.
Secondly; Tolkien’s “canon” on whether or not the Valar create life changed radically over time. In some of the earliest drafts of the Silmarillion the Valar operate much more like the Norse pantheon rather than angelic beings. In that version the maiar are their biological children, and Melko(r)’s monsters are bred from him very much like Loki’s children.
As to whether or not his creations hate him, I remind you that just about everything ever written for the Silmarillion is from the perspective of elven scholars.
What Melkor did with the elves was recreation.
Recreation is a form of creation with the classical definition of bringing something into existence. Recreation takes something that already exists but forms it in terms of looks, behavior and so on to get something that had existed before. Without the intervention of Melkor the elves would not have become Orcs as there were no vectors for this kind of evolution to happen.
Melkor did, in order to create beings fit for his purposes, something that is equal to the way humans have breed dogs to fit their needs. In order for Melkor to create Orcs or to breed dogs something preexistent had been taken. Melkor used the elves as a basis and has reform them in shape and behavior, to recreate them into Orcs as much as humans have taken wolves to breed and recreate dogs.
On a side note of evolution:
It is impossible without getting a laboratory involved to create looks and behavior that have no root in the original being. For dogs it means that floppy ears, curled tails, spotted fur and a gentle nature are already genetical coded in the wolf. And for the Orcs this technically means that their heinous looks and their cruelty are already coded in the gens of elves but lay for them dormant.
Around 1959 a Russian, Dmitrij Belyaev, started to breed foxes with the goal to make them pets. In order to do so he selected 30 male and 100 female from a fur farm who were already tamer then their wild living relatives. From those 130 foxes he selected those who proved to be the least aggressive and started to breed them. From the second generation he again selected those who were again the least aggressive and breed them. He repeated the process until every being of a population was tame and could be touched by humans, some even looked actively for human contact. But the tameness of the foxes was not the only thing that increased. Around the 10th generation there were more and more foxes with spotted fur, floppy ears and curled tails - much like dogs.
But now back to Melkor and his Orcs. If Melkor had just breed Orcs to increase their evilness. He could have taken only elves that were more aggressive, evil-minded and more durable then others to breed further resilient and more evil ones. The disfigured look (like sharper and pointier teeth, smaller evil-glowing eyes and/or tumor-like humps over the whole body) could have increased through the reduced gene pool and were originally a side effect that proved to be useful for Melkor’s purposes. After all a vile look increases the fear that Orcs induce when they raid elvish and later human settlements just like the floppy ears increase the cuteness of the foxes.
And, Wesley, don’t let yourself be put down by people who can only think in small canon boxes. Fanon lives through all those various interpretations of canon. Keep on going! Your thoughts and thesis are very interesting to read.
This. THIS THIS THIS. Mythology and biology I am the happiest nerd ever right now. Kudos for everyone.
