Actually, from my observation most christian religions, (excluding the wacky), have the same tenets with variation in interpretation of heaven/hell etc. How you are supposed to behave as a Christian do not differ. They differ in how they punish.
Within all religions are people who live their lives as good, honest, productive people. They may be missionaries, or work in local communities and they spread their gospel more than JW's sitting by literature trolleys. That is the honest truth.
If you are truly interested, honest and open minded, Formerbrother, you will see there is much good being done outside the JW organization. If you are like I used to be, I never noticed or cared, so I didn't see it. Just because I believed everybody else was bad didn't make it true. It only made me ignorant.
I wish you strength for the journey.
