"It's a legend. Nobody is for certain he existed or not. Plus, most modern versions are way off. Search more on it, you'll find plenty of different versions of the story. He might be just an urban legend. I'm not saying he isn't, because I think he is, but I just think his story was a lot different and modern society has altered it quite a bit, but they didn't alter the main purpose of his story: murdering people while they expected a shave or trim. Plus, some more older versions said he just killed his victims to take his money, not in rage of him thinking his wife was dead."
