After the tragic death of his only son Jett in January, actor John Travolta is reportedly questioning his faith. According to the Daily Mail, Travolta is considering leaving Scientology, the cult-like religion of which he is a very public follower and benefactor. Scientology doesn't acknowledge the existence of autism, the disease Travolta's 16-year-old son is said to have suffered from, and Travolta apparently regrets adhering to their medical instructions. "There have been strong rumors coming out of Scientology that John Travolta is disappointed that the religion was not able to help his son more," said Rick Ross, a lecturer on Scientology. "It's led him to question his faith." The church keeps files with embarrassing material on its celebrity members to prevent them from speaking out against the religion if they choose to leave, Ross said.
