Considering this child patient, you're saying the family hasn't clarified the doctor's treatment plan and directly asks if it's necessary to donate bone marrow. Do you think the parents are rushing to donate for their child? You're thinking too much. Doctors have seen all kinds of ethical dramas in clinical practice.
You should also know, even if parents love their child very much, they at least need to plan for the child's future. For example, whether the subsequent treatment costs need to be borne by the parents, and if the parents become physically weak after donating, how will they continue to care for the child? These practical issues need normal parents to carefully consider before making a decision. Moreover, everyone has a kind heart; ordinary people will definitely consider the donor and have concerns—it's a common human instinct.
