As our technology rapidly advances, designer babies and other bioethical issues are fast becoming possible. Instead of solely being considered in economic terms, or in terms of accuracy and desirability, ethical questions should also be asked such as ‘is this a good thing to do?’. This article considers whether moral people would ‘design’ and genetically engineer their babies and applies the moral theories of virtue ethics, deontology and utilitarianism to help guide our ethical decision-making in relation to this complex issue. Even if we can do something, we should pause and consider whether or not we should.
