Yes, and that is exactly the moral dilemma Tolkien had. He believed that killing orcs are wrong unless there is a very good reason, so he would have thought it was wrong to kill demons unless there is a very good reason.
I don’t think he does. The whole point of Sauron trying to enslave Middle Earth is exactly the justification you need for the mass slaughter of the “enemy”. If the orcs were spending the days idly farming and smoking hobbit pipes, you would have a whole other argument against genocide.

I think the orcs/demons being hell-bent on killing humans is a sufficiently good reason.
Tolkien disagrees with you.

Did you read the wiki page I sent? Fighting an army isn’t the same as committing a genocide.
