My Sister's Keeper

this movies based by novel written by Jodie Picoult
tells the tale of Fitzgerald family,
after their daughter is stricken with leukimia, a couple conceives a younger sister who can provide a donor match, but the family is torn apart when, after years of medical procedures, the healthy younger sibling sues her parents for the right to decide how her body is used..

Anna is not sick, but she might as well be. By age thirteen, she has undergone countless surgeries, transfusions, and injections to help her sister, Kate, fight leukaemia. Anna was born for this purpose, her parents tell her, which is why they love her even more.

But now she can’t help but wonder what her life would be like if it weren’t tied to her sister’s…and so she makes a decision that for most, at any age, would be too difficult to bear, and sues her parents for the rights to her own body.

Ps,
"if you use a morally wrong way to save the lives of your children, is that makes you a bad mother?"
