Do you think it is worthwhile or not?

Hi, my dear friends, welcome to wwenglish forum. Have you ever read the stories of the little Mermaid or the Nightingale and the Red Rose? Do you think it is worthwhile for the little mermaid to sacrifice her life for the princess in the condition of the princess knew nothing about it. Actually after I have read the Nightingale and the Red Rose, my heart goes out to the little nightingale. Poor little bird, she is so kind as to be foolish. In order to get the student to win his “ true” love, she dedicated her heart’s blood to redden the white rose. She died anonymously in the long grass, yes, anonymously. No one knew her, even the student. At last, the rose, sealed with her blood, was thrown to the gutter and a cart wheel ran over it. What comments should we give to the nightingale? A tragedy? A heroine? Do you think it is worthwhile for the nightingale to do that, especially anonymously? What’s your point of view to the stories, do you agree with unselfish devotion ano
