Are Authors Psycho Because of the Stories They Write

I think that people shouldn't judge authors by there stories. Because maybe when they wrote that story that seems sick and twisted, maybe they were angry or not in a good mood. Its kind of like the phrase don't judge a book by the cover. For example Edgar Allan Poe I don't think he's psycho, I say this because some of his stories are kind of sick and twisted like Mask of the Red Death, maybe he was angry or a sickness has took some of his family members and he was expressing his feelings. But some people think that since authors write sick and twisted stories they are psycho but I don't think that. maybe some authors are pyscho maybe some are not only they would know if there psycho.
