Johann Hari details some of the pernicious ways religions exploit the desire for heaven:
Even some atheists regard heaven as one of the least-harmful religious ideas: a soothing blanket to press onto the brow of the bereaved. But its primary function for centuries was as a tool of control and intimidation. The Vatican, for example, declared it had a monopoly on St Peter’s VIP list – and only those who obeyed their every command and paid them vast sums for Get-Out-of-Hell-Free cards would get them and their children onto it. The afterlife was a means of tyrannising people in this life. This use of heaven as a bludgeon long outlasted the Protestant Reformation. Miller points out that in Puritan New England, heaven was not primarily a comfort but rather “a way to impose discipline in this life.”
It continues. Look at Margaret Toscano, a sixth-generation Mormon who was a fanatical follower of Joseph Smith in her youth. Then she studied feminism at university. She came back to her community and argued that women ought to be allowed to become priests. The Mormon authorities – the people who denied black people had souls until 1976 – ordered her to recant, and said if she didn’t, she wouldn’t go to heaven with the rest of her family. She refused. Now her devastated sisters believe they won’t see her in the afterlife.Worse still, the promise of heaven is used as an incentive for people to commit atrocities. I have seen this in practice: I’ve interviewed wannabe suicide bombers from London to Gaza to Syria, and they all launched into reveries about the orgy they will embark on in the clouds. Similarly, I was once sent – as my own personal purgatory – undercover on the Christian Coalition Solidarity tour of Israel. As we stood at Megido, the site described in the Book of Revelation as the launchpad for the apocalypse, they bragged that hundreds of thousands of Arabs would soon be slaughtered there while George Bush and his friends are raptured to heaven as a reward for leading the Arabs to their deaths. Heaven can be an inducement to horror.
