Ken Irving was my next door neighbor when he and his wife were first married. I had and have no connection to the Irving family aside from buying their gasoline and other products and services at times. I never knew Ken, but I can tell you he was a most gracious neighbor. He knocked on my door one day to show me and my wife the plans he had for a fence he was thinking of building between our properties. He was concerned that we not have a problem with what we had in mind: and I'm not a person of any particular importance.  

My heart goes out to him. I've had mental health problems myself. 

His father Arthur has shown much generosity to the citizens of Saint John. He has done many good things and my heart goes out to him too. Who can doubt that these matters have not caused great suffering for him too.

I think there are degrees of mental health. The first step on the 8-fold path of Buddhism is Right View - properly appreciating how things are and why. It isn't easy for anyone.
