seems to be a good place to gather truly great people who have high morals and are trustworthy
I understand what you're trying to say but think about it for a minute. Most parents teach their children to be honest, trustworthy and to have good morals. Hindu's, Muslims, Christians and even (shock horror) atheists all are mostly good people trying to do the right thing.
If you want to decide whether the morality of a particular group is something exceptional it has to be on the unique identifiers of that group.
So;
Shunning - immoral.
Instilling sexism and homophobia - immoral.
Abusing developing young minds with a demons/Armageddon worldview - immoral.
Teaching anti-science - immoral.
Sacrificing lives over blood treatments - disgracefully immoral.
For the record, I think most Jehovah's Witnesses are good people but the morality specific to Jehovah's Witnesses is appalling.
