People do not choose to believe or not believe in a god. We arrive at conclusions due to a number of factors and influences. Our education will play a part in how we assimilate the information and experiences that we are conscious of.
If someone is unable to accept Bible based religions they should examine Eastern spirituality. I have friends who have found peace and comfort in them.
To me freedom from the religious slavery of following Jesus, or any invisible being who will decide my fate, is worth any price. But if someone is happy in their religion they should stay, even if they are JWs.
