I don't know about those specifics. Sure it was stupid to want a world with just the 10% that can use magic since that doesn't really solve anything since mages are also born via non-mage lineages, but I don't see it as "evil motive" per se, I'm sure he doesn't "enjoy" eliminating millions of people, he just believes it needs to be done. Even he admitted he was disillusioned and he died with the knowledge that he was wrong in his research. I feel sad for him. Glad he died, but still sad. I don't see your argument on vast majority part though. Humanity was originally very small during the time of dragons so it is obvious that they do just fine with a small population, same applies IRL. Ironically Zeref does go somewhat along what Hades thought, though Zeref knows that mage or non-mage is irrelevant since they are all human and so wants to purge the problem entirely, which is great if not for the fact that he must be stopped for the sake of "Good/freedom/justice prevails!" and "Humans can change for the better" concepts that the media likes to make the public swallow.
