He killed them because they expelled him from the Jehovah's Witnesses - Canal de Noticia (Venezuela), Nov 28, 2017 - Two JWs found murdered
However you look at this it is a tragic event. One thing which the JW teachings offer people is an identity. To be connected with others is a human urge. If you have very little going for you in life then simple things like belonging to a religion can mean a lot. If you are then expelled from that community your lifeline has gone and if your reasoning and emotional control is poor then this situation could arise although fortunately this must be rare.
I did read of a JW missionary in the Pacific islands who killed his two missionary companions.
It´s a tragedy for both JW´s and exJW´s.
It plays right into the hands of JW propaganda... exJW´s are crazy psychopaths who will murder people.
There has been more than one case of people "snapping" after being disfellowshipped. It´s a cruel and very traumatizing experience.
Apart from the appalling deaths there is an absurdity in this news in that the revenge for expulsion makes membership of JWs look like a desirable thing, worth killing for.
