“ [about suicide] And why is it the biggest sin of all? All your life you're told that you'll be going to this marvellous place when you pass on. And the one thing you can do to get you there a bit quicker is something that stops you getting there at all. Oh, I can see that it's a kind of queuejumping. But if someone jumps the queue at the Post Office, people tut. Or sometimes they say, “Excuse me, I was here first.” They don't say, “You will be consumed by hellfire for all eternity.” That would be a bit strong. ”
