If we only read Lyle's letter, we would be deceived because Lyle used kind, gentle words in the letter in order to read for friends to pretend that he was very merciful overseer. 
All the mess in Vietnam people blamed it on Darrel. In fact, Dale Shutlz was standing behind.
After Dale and Darrel kicked Châu out, the friends showed opposition, Dale pretended to send Jim Girton, overseer of Phillipines, representative of Korean overseer, Parkistan overseer. They came and left without any correction. Friends were disappointed.
Then Dale sent his brother, Lyle Shutlz to replace Darrel. Everyone filled with hope at first. But in fact he caused the mess many times bigger than Darrel. The division was more serious. So saying that Lyle Shutlz came to resolve the mess is only an illusion. I think uncle Châu was tricked by Lyle into submitting him completely.
I didn't see any honesty in these people.
One time my wife asked Lyle: " Do you come here to defend for your countryman Darrel or you defend for the Kingdom of God ?"
We experienced them so I can draw a conclusion :"Don't believe their words until you see their action, their spirit"
