mewburn was a personal friend of mine, about 1976 we started falling away from the truth into drink and the like, he wasnt disassociated officially,just not attending meetings much, like myself.
Purkiss is a little harder to explain, I reckon he did himself when I was about 30, I was out by that time and i heard about it on the grapevine must have been about 1986, his status re org at that time I cant say. Both persons frequently spoke to me about personal inadequacy re not being worthy of Jehovahs love and mercy.I long suspected homosexual leanings in Lawrence.
Based upon these two experiences, (the only ones I know of) it seems possible that people leave the org, step into the world, become involved in condemned behaviour along the lines of "leave the org
and you will fall into decadence and despair"(a self fulfilling WT prophecy)and they cant cope and off themselves.
hope this is usefull.
