Any org that is heavily underpinned with the need for 'obedience' attracts some people who will seek to be more obedient than ever they will develop a "hyperactive conscience" and be ever looking at ways to check that those around them are also going down that obedience track. They will create a whole vipers nest of rules to do this by. E.g. we are seeing this is the Islamic world where the most heinous crimes are committed against other Muslims because of some perceived error on their part.
The wt seeks to justify their proscription of others in the name of God also.
If the the wt were followers of Jesus (Yeshuah) the Christ he preached love and a much abused term today tolerance; well how different would the experience of being a jw be? It is likely this site and other slike it would not even exist!
The wt at its worst reminds me much of the Nazis where reporting fellow citizens to the gestapo was the norm. But note too that the 'reporters' are probably of the hyperactive conscience (class). Yet, when some of those in charge are reported for child abuse or criminal assault of their wifes. then the wt system covers up its most 'loyal'.
