DON'T THINK OF IT AS DYING, said Death. JUST THINK OF IT AS LEAVING EARLY TO AVOID THE RUSH. - Terry Pratchett

No one is actually dead until the ripples they cause in the world die away...

"There were people who called themselves Satanists who made Crowley squirm. It wasn't just the things they did, it was the way they blamed it all on Hell. They'd come up with some stomach-churning idea that no demon could have thought of in a thousand years, some dark and mindless unpleasantness that only a fully-functioning human brain could conceive, then shout "The Devil Made Me Do It" and get the sympathy of the court when the whole point was that the Devil hardly ever made anyone do anything. He didn't have to. That was what some humans found hard to understand. Hell wasn't a major reservoir of evil, any more than Heaven, in Crowley's opinion, was a fountain of goodness; they were just sides in the great cosmic chess game. Where you found the real McCoy, the real grace and the real heart-stopping evil, was right inside the human mind."

Everyone's heard of Erwin Schrodinger's famous thought experiment. You put a cat in a box with a bottle of poison, which many people would suggest is about as far as you need to go.
