JWs do not believe in the deity of Christ, Christians do. JWs do not believe in the trinity, Christians do. JWs think they might be a part of the 144,000 witnesses spoken of in Revelation, but they are not Jewish, for the most part, so this is not possible. In short JWs reject the person and work of Christ and are not saved. They think He is just a messenger from God or merely an angel. My feeling is they are people who like being religious. Christianity is not a religion but a relationship with God, based on grace, that starts at the moment of salvation and goes on forever. But they rejected Christ and have no choice but to fill the void in their souls with lies.
I looked up the current leader of the JWs about 5 years ago, then looked up his net worth. At that time he was worth 900 million dollars. So I would say the JWs are not about truth but about making their leaders very very rich. I think of it as a religious pyramid scheme to make the top dogs rich.
