Sure. Hindsight thirty years later is a difficult thing to argue against no matter how absurd and disingenuous the argument it upholds. Hypothetically, should you ever create something like Watchmen after signing a contract with DC, rest assured that DC/WB lawyers will find a new loophole to screw you over to get all the money. That's what happens. They'll find a new loophole just for you because of the special little unicorn you are.
Again. He did that, and everything seemed fine on the surface. Nobody could have predicted or anticipated DC to kneecap him in the specific way they did. This is basically you declaring against the actual record and evidence that Moore was some idiot.If his creations were THAT important to him, he could have taken the contract to a contract attorney to have them look it over for him and warn him of what could happen, if he didn't.
Well the good news for you is that a substantial chunk of Moore's output isn't superhero work at all. If Moore never wrote superheroes he would still be valued as a great writer in comics for stuff like:
-- The Ballad of Halo Jones
-- V for Vendetta
-- Brought to Light
-- A Small Killing
-- From Hell
-- Lost Girls
-- Promethea
-- The League of Extraordinary Gentlemen
-- Necronomicon
-- Providence
-- Big Numbers
-- Also a bunch of classic short comics for smaller publications such as "The Bowing Machine" and "Pictopia" among others.
The fact is that the majority of Moore's career has been in independent comics unaffiliated with the Big Two, most of it outside the superhero genre. The time he worked for DC that was basically a five year stretch of his career. That's it from around 1983-1987 or so.
