I don't think people like Nolan in the same way as Homelander or Tyler Durden. He's obviously evil in the first season, and in the following seasons he goes through a very slow redemption arc, mostly centered around whether he deserves or wants to keep living
spoilers
Nolan is a soldier of a fascist empire, and at the end of season 1 slaughters hundreds of innocents and beats the shit out of his son. After that he considers suicide and basically only lives out of guilt, trying to keep his children alive. He intends on letting the fascists execute him, but is saved and finally decides to turn against the fascists in season 3.
He's basically a former fascist soldier who now wants to destroy the fascist empire, rather than a proud fascist villain.
