Indeed, most of us have met someone who could become that murderer; the toxic personality whose progress through life depends entirely on their control, manipulation and abuse of those less powerful.
While there are women with toxic traits who murder for money or power, and it is true that more men than women are murdered annually, it's also a truth, universally acknowledged, that most men are killed by other men, and that male intimate partners pose the greatest risk to women.
This explains why men have their very own label - toxic masculinity, which involves an insidious and damaging sense of entitlement and belief in male superiority.
Read the fascinating stories of the toxic men and women who kill, including:
Borce Ristevski, who killed his wife Karen
Patricia Byers, convicted of killing one partner and the attempted murder of another
Arthur Freeman, who murdered his young daughter Darcey
John Sharpe, who killed his wife Anna and daughter Gracie.
