One must never forget with JW there is an irrational explanation for every conceivable situation.
-When a "worldly person" succeeds = they are evil and "Satan is blessing their wicked path in the last days of this system to try and entice God's Servant's to turn away."
-When a "worldy person" fails = this is a testament that "the world is a lonely, dark, corrupt, wicked place and that any JW who stray from the flock will suffer a similar fate."
-When a JW succeeds = very simply a matter of "Jehovah is surely blessing their efforts."
-When a JW fails = this is an example of "persecution and trials a loyal servant of God was prophesied to endure in the last days of this wicked system of things" OR, if the JW was fringe and subject to gossip.. they turn on themselves and say secretly "this JW was spiritually weak and deserved his/her fate"
There is no rationalizing with a cult. They have an indoctrinated mindset and will provide an explanation, no matter how illogical, for EVERYTHING.
Just my 2c from experience.
It is not religious persecution for an informed person to expose publicly a certain religion as being false, thus allowing persons to see the difference between false religion and true religion.
