Funny. I always got the impression that Morgana knew exactly what was going on in s02e12. Merlin wasn't responsible for Morgana's turning. The more people he told his secret to, the more likely that every passing patrol COULD be Uther sending men to apprehend Merlin. He couldn't risk it. He was afraid of telling her the truth and supporting her through the change (though, in truth, he did support her as best he could). His true crime was in not confronting her after she'd turned in Season 3. The writers seemed to deliberately avoid the conversations that the audience was desperate for between Merlin and Morgana. He never once reminded her about how he'd kept her secret, and how he'd sent her to the druids, and about how he and everyone else had helped her countless times (particularly Arthur, who stood up for her against Uther on a number of occasions). So, Merlin could have redeemed Morgana a lot earlier but he wasn't responsible for her turning. Not like with Mordred, who he has been suspicious of since the get-go, with good reason.
