I have noticed that many witnesses are very self centered and selfish people as a result of "leaving everything in God's hands to correct"
What I mean is, because "the kingdom will fix poverty, the homeless, poor, underpriveleged, etc...." it means they can just pass by those in need, or fulfill their natural human desire to help (if they have it) by just giving literature!
So, just preach to those in need, and then you can feel good and smug about yourself!
True, there are some very loving people in the org, some who would give the shirt off their back to someone (usually a fellow beleiver). But generally witnesses have been taught to supress or rid themselves of any human niceness by having "the kingdom will fix it" drummed into their brains!
Just my two cents worth of observations...
