When Superman was forced to fight Batman by Luthor, he made his way to Gotham conflicted on whether he wanted to kill the Bat or appeal to him and ask for his help.
Superman made the sensible choice and decides to come clean to Bruce and he starts with "Bruce, I was wrong, you have to listen to me..." Now, what did Superman mean he said he was "wrong"? What was he wrong about that he made aware to Batman earlier in the film?
Personally, I think Clark somehow figured out Lex was behind the whole prison stabbings of branded criminals thing, which only provoked Superman the first time to confront the Bat. However, this was never really explained and I was just wondering if there was an explanation in the film about this?
