Was Rosemary brave or cowardly?

The previous Receiver-in-Training and The Giver's daughter, she was deeply affected by her new knowledge of pain and chose to apply for release, delivering the lethal injection to herself. I don't think this was cowardly as the pain was too much for her. These people were not used to emotional pain to begin with.

that she was brave because she holded so much pain and share love the community
