Professor Jonathan Herring co-authors new study challenging perceptions of ‘mercy’ killings

Exeter College’s DM Wolfe-Clarendon Fellow in Law and Professor of Law, Jonathan Herring, has co-authored a new study examining the circumstances surrounding domestic ‘mercy’ killings in England and Wales. Published in 2026, the research challenges common assumptions about these cases, revealing significant patterns of gender inequality, violence and a lack of consent. 

The study, Domestic mercy killings in England and Wales 2007–2024, co-authored with Hannah Bows and Merili Pullerits, explores cases commonly described as ‘mercy’ killings and questions the extent to which they reflect popular perceptions of compassionate acts intended to end suffering. 

The findings reveal that, contrary to the assumption that such cases typically involve individuals with terminal illnesses who have expressed a wish to die, most victims are women killed by their male spouses. Many cases lack evidence of an explicit request for death or consent, while violent methods of killing and homicide-suicide are recurring features. 

The research also highlights the prevalence of dementia among victims, raising important questions about vulnerability, autonomy and the ability to consent. These findings challenge the frequent association of ‘mercy’ killings with assisted dying, particularly where individuals would not have the capacity to make such a request. 

Professor Herring’s research explores issues at the intersection of law, ethics and human relationships, including vulnerability, care and the legal protection of individuals. This latest study contributes to wider discussions about how domestic killings are understood and represented, and the importance of recognising gendered patterns of violence.
