Corrected entry: One of the thieves robbing the museum wishes he was never born. His wish is granted, but the movie should have ended right there. Since he was never born, the museum would have never been robbed, there would never have been a shoot out that damaged the statue of Ahura Mazda and caused the "fire opal" to be found, hence the Wishmaster would never have been released.

Correction: You say it yourself - ONE of the thieves, plural. The other guys could have done it without him, or another of their friends would have completed the party.
