How long will negative entities still be able to exist on the planet?

Or as the late, great Bill Hicks put it:

The world is like a ride in an amusement park. And when you choose to go on it you think it's real because that's how powerful our minds are. And the ride goes up and down and round and round. It has thrills and chills and it's very brightly colored and it's very loud and it's fun, for a while. Some people have been on the ride for a long time and they begin to question: "Is this real, or is this just a ride?" And other people have remembered, and they come back to us, they say, "Hey, don't worry, don't be afraid, ever, because this is just a ride." And we kill those people.

(I know a lot of copies of this quote cut off the final punchline, but to me, that's what brings it full circle. Most people don't want to hear that life is just a ride, because they think that makes it less fun and\or interesting. And so what if prophets tend to get killed? It's just a ride. Everyone disembarks sooner or later.)
