I didn't see much 'congregational' dishonesty (not saying there wasn't a lot there but I didn't see it!) I did see a lot of JW businessmen who would have put the Enron guys to shame with how they treated 'worldly people.'
I once asked a brother how he could justify what was basically stealing and he said 'they're just worldly people, they're gonna die soon anyway!' I saw that attitude a lot! In fact it was so prevailing that when I was a newbie on this site I started a thread similar to this one about it! I once had a brother tell me that he was doing a lot of extra 'free' work for this house he was building on the beach because 'after this guy dies in armageddon I'm going to live there!'
What a bunch of sick deluded morons!
