Joseph Knox, one of the most prolific and well-known serial killers on the planet. A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed. So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar? Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world
