Kajune is right, IMO. She said it herself: she'd rather die a million times and murder her own brother a million more before going back to her prison. I don't think it has to do with the imprisonment itself, but rather the prison she was in. Like she told Dean once she was released, "I haven't felt this peaceful in a long time".
