And he was so fucked up over that that he exiled himself into space which opened a can of worms with Mongul. If Superman could have just gotten over himself, owned what he did, Coast City would have been fine and Hal Jordan would not have decimated the Green Lantern Corps.
Guy I think you have confused things. Coast City was destroyed post-Superman vs Doomsday. Supes was dead at the time and everyone believed the Cyborg Superman was the real one. Cyborg Supes blasted through the Eradicator and decimated Coast City. Which lead to Hal Jordan going mad with grief and becoming Parallax.
