Bioethics looks at benefits and risks, and also at balancing pursuit of individual autonomy with the duties of justice.
Love is a broad term, but includes the concepts of balancing benefits and risks.
Love is the desire to do good and the need to avoid doing harm. It includes love of others as oneself, the respecting of autonomy. It also includes the idea of justice, loving others and sharing what we have - distributive justice. It includes technology assessment in the biological sciences, and medical and environmental issues that are new and old. There have been some claims that bioethics is only an issue for countries who have sufficient resources, wealth and time to decide not to introduce biotechnology.
