User blog comment:Morgana High Priestess/Could have Morgause brainwashed Morgana?/@comment-5102537-20130311075520/@comment-5102537-20130316142303

"It wouldn't have made her confident enough to announce the fact that she had magic but I would have expected that she would have reconsidered her belief that Uther hated magic more than he cared for her, and that she wouldn't have felt as frightened or angry as she once did."

Exactly my thoughts. As it seems, Morgana didn't care anymore about reality and she didn't want to be loved by Uther or anyone. Which would contribute to the assumption that she either was brainwashed/enchanted or that she simply lost her mind.

When Uther asked her in his cell if she really hated him so much, rather than casting a stone at her for having magic, which he obviously didn't even care about, Morgana should have realised that her feelings for him was the only thing that mattered to him. And when he went broken and depressive, she should have realised that, no matter what she had been thinking and what she was afraid of before, he wouldn't have killed her (since he didn't do it).

So she either was really brainwashed, like Gwen was when she tried to kill Arthur, regardless his true feelings for her, or she was mentally disturbed and had no interest in love, family and harmony anymore but considered sympathy and love to be the very things that would help her to destroy her "enemies" by using it against them.
