The donors' complete autonomy and voluntariness for donation is the core of ethical acceptability of living organ transplantation.Deep in the donors' heart,the awareness of self-respect and the altruism are two contradictory tendencies both in psychology and behavior.As the existence of the tension of self-respect awareness and altruism,it becomes particularly difficult and complex for the living organ donors to make autonomous decisions.This paper analyzed the tension of self-respect awareness and altruism,discussed the emotional and ethical contradictory,and proposed some suggestions based on this,hoping to provide a good internal environment and external support for the potential donors to make reasonable free decisions and guarantee the ethics of living organ transplantation.
