Here's the guy I was talking about :3 His name is 1:30.

This man had a criminal record of homicide. He's killed over 30 people. He's kept this secret from the society. After his ban, he died years later. He was then reincarnated as a demon who was still on a mass murdering spree. He however still fears death in his current state, which is why he fears and must obey Purgatory. The other irony...his birthday is on Janurary the 30th, he was born at exactly 1:30, and he died the same day at the same time...at age 30
