Voluntary stopping of eating and drinking (VSED) is an increasingly popular method by which patients are choosing to hasten death when life feels unbearable. This formal act of suicide often leads to distressing symptoms, for which patients then seek palliation by medical professionals. The intentional act of hastening death is always an evil act. A Catholic physician must understand the moral implications of participating in any phase of the patient’s planning and execution of the VSED process, including cooperation in evil and scandal. The Catholic physician must strive to develop a well-formed conscience and then be prepared to exercise his or her right to conscientious objection while offering an example of true compassion for the sick, the suffering, and the dying.

Despite great interest in the field of gene editing, sparked by the advent of CRISPR/Cas9-mediated applications, the personhood of tripronuclear zygotes has not been addressed appropriately. 3PN zygotes are discarded as medical waste, and their use as models for human genome editing is becoming increasing common. 3PN zygotes possess an extra set of chromosomes, which often leads to severe genetic abnormalities; they are dismissed as “nonviable embryos” and treated as an ethically acceptable alternative to human embryonic research. However, given the development cycle of 3PN zygotes and the qualifications for human personhood assessed, there is compelling evidence that 3PN zygotes are indeed human persons. Although genetically disadvantaged, they deserve the same respect as do genetically normal human zygotes.
