She suffered from insomnia because of the euphoria she felt!
This question is ridiculous. She played a part in his death, so I don't see how she could have suffered!

you could see how truly deeply affected she was. he was her father..even though he didn't loved her as he loved Arthur...and refused to give her his name and her rights as a princess

She said she felt his pain and didn't look all too happy when Agravaine wanted to celebrate. She made up an excuse.
He was the one that always cared for her and looked for her for a year when Morgause took her. If only he'd acknowledged her, she wouldn't have killed him.

She didn't suffer too much because she wanted him dead. If she ever did kill Arthur or Gwen though, I think she would handle it badly and feel guilty.

He was her father, after all. She was still a human.

She killed him for the throne that's why she hardly suffered of Uther's death.... Actually I feel sorry for Uther he really loved Morgana and her betrayal strongly broke his heart !!!

Uther had a very weird way of 'loving' his daughter. Chaining her, denying her the right to the throne...

Yeah I think she kinda did even if she won't admit she cared about him deep down

she is bidimensional character
