If you really thought your dead loved ones were up in Heaven waiting for you, wouldn't you....commit suicide? Everyone who doesn't gleefully blow their brains out lacks faith.
Oh, oh, right, the scam-meisters threw in the "suicide is a sin", load of horse-hockey, because a bunch of dead cultists can't plow the fields, and fill the collection plate.... Helluva racket they have going. They thought of everything.
Whether or not your Magic Kingdom exists is irrelevant to my statement that it is sad you need such a fairytale to make this life worthwhile.
I really don't understand why people need an after life to enjoy this life. I enjoy life so much without hurting others. Edit: it's a puzzle to live through.
