Why did rosemary ask to be released?

Rosemary asked to be released because she felt overwhelmed by the weight of her memories and emotions after experiencing the depth of pain and suffering that comes with the memories of others. In "The Giver," she realizes that the burden of knowledge and the complexities of human experience are too much for her to bear. By seeking release, she chooses to escape the painful realities of her society, which values sameness and conformity over individual experiences and emotions.
