"Forgiven" implies Picard did something wrong, he didn't.
What happened was that Sisko just realized Picard was no different from him, another victim and wasn't deserving of any scorn.
Right. Well, that's what *should* have happened in the show. For all wthe viewer knows, sisko still hates picard. Theres no payoff scene where he shows that he doesnt hold it against him, unfortunately.
