Do you think Walking Dead-esque villains exist Romero's universe?

Do you think there are people like the cannibals, Negan, and the Governor in Romero's world?

Both universes are almost identical. If you were to remove the "evolving intelligence" factor of Romero's movies (i.e. Bub, Big Daddy, etc.), they could actually co-exist since the show and Romero's films take place in different states/cities.

Between the two franchises, The Walking Dead has the advantage of world building in its favor, something the Romero films don't have (not knocking them, just an observation). While watching Night/Dawn/Day, I always found myself wondering what else is going on outside that farmhouse, mall, and bunker. We get some glimpses, tidbits from radio/TV broadcasts, and such, but it never really fully explored the undead landscape the way that The Walking Dead has.

Given that their universes are similar in many ways, it makes me wonder if similar like-minded psychopaths like Negan might have popped up during Romero's scenario.

Thoughts?
