Madam, - Gary J. Byrne claims (September 20th) that Father Rory's act of kindness to Michael Hull in Lourdes (September 18th) had nothing to do with religion - that this type of behaviour is genetic.
What is the name of the relevant gene? Who discovered it? And why does it malfunction to such an extent in people such as Mao, Stalin, Hitler or, among less colourful examples, the Dublin gangland killers? — Yours, etc,
