The second patient, however, cannot agree to donate his kidney, because one of the main reasons is that he is afraid and does not have “the courage to donate”9. We therefore see at this stage that it would be better for the father not to donate his kidney, because that would not bring him any happiness, while the daughter has two options for everyday life, whether on a personal level. basic or professional basis, difficult scenarios, or also called moral dilemmas, are present. Depending on who the person is or what their beliefs and value systems are, the problem can be “solved.” In this particular case, questions arise as to whether it is morally right to lie to family members when something can be done, ignoring the fact of its consequences. The case will be explained in detail later, including the patient's condition, but to answer this ethical question, two theorists will be presented for and against. On the cons side, deontologist Immanuel Kant will be presented with his theory that lying is prohibited under all circumstances, while on the pros side, John Stuart Mill will be presented for the utilitarian theory that the decision that brings the most happiness is the right decision. After discussing the case, my personal view on what is right will be stated along with my own reasons that lying is the right decision to make.
