Allot of those don't actually want their nemesis dead as much as the just want to terrorise them.
Joke has said on more than one occasion that Bats is to much fun, or gives hims something to live for. Even when he had all the power in the universe he couldn't keep Batman dead long. He just felt empty without his counter part.
Same with Sabretooth. Wolverine gives him a toy to play with that will play back.
Luthor definitely wants Supes dead. But then again so do I! ermm
Venom wants Peter dead form time to time but its normally just momentary hatred and it eventually subsides when Eddie is able to suppress the symbiote. The rest of the time its jus bullying and trying to prove he's better.
Magneto doesn't really want all human's dead. If he did then they would've been in HoM. Plus he's sided to protect humans a few times. It more of jus blinded by his anger over what happened to him and his family. He sees allot of mutatan hating humans as those same Nazi's that killed and tormented those he loved. I hate when Magneto's portrayed as this uber evil villain type. He's best written when he's just trying to protect his people and going to far when he lashes out. He's trying so hard to stop what happened that he's becoming the very thing he hates. Deep down he's not a bad person.
Doom, on the other hand, yea he REALLLLLYYYYYYYY hates Reed. I mean about as much as one person can hate another. IMO he definitely tops the list of pure hatred. But if you read closely its just because he is so arrogant and vain and has such pride. He actually envy's Reed incredibly because he sees that he may be his only superior. It why he wants anything Reed has and needs to take it from him by superiority.
Of course Victor would never admit this. Even to himself.
