Dying as a goal

Here's something that doesn't make sense to me. Why don't super religious people want to die? Sure suicide is a sin and all that, but I'm sure there's ways to increase your chances of dying without committing suicide. Now most people sin all the time and have good reason to not want to die. They're not sure if they qualify for a good afterlife. But what about those people that truly believe that they've done everything they are supposed to do and will be going to heaven for sure? Religious extremists that have a flawed sense of their faith tend to have no problem dying, but they do terrible things in the process. But what about your everyday devout person? If they truly believe that when they die they get to live on for eternity in perpetual bliss, why don't they constantly WANT to die? Getting hit by a bus should be the best thing to happen to them, by their own logic, right?
