In 90's there was a cult that thought they were going to get taken into the heavens in a space ship. Several of them got castrated to help them clear their mind, 'cause no one does those kinds of things in heaven. Once a room was found with 30 Heaven's Gate members who had commited suicide. They thought they were leaving their bodies so they could get into the spaceship, which was behind some comet that had happened to show up.

They claim to be Christian, but they're a cult, and no one is quite sure what they believe anymore. There's a lot of information about them online and wikipedia will link you to their official website as well.
Poor Sod: I'm lost, confused, self deprivating, and desperate. I should go join Heaven's Gate Cult! A cult would fill the void!
