I do not think Edgar Alan Poe is a disturbed man, and you can't judge everybody based on their writing. The point on writing is to be creative, and sometimes people write disturbing stories to let out their anger or emotion. Edgar Alan Poe did write a lot of disturbing stories, but maybe this was because he wanted to let out anger like others or to just be creative. When people write stories they don't want to write anything boring so they may write about death or maybe even Cinderella. Most of the time it's not what the people write about it's how they write it. So I don't think that people should judge writers based on what they write, maybe one day you will write something like that too. Does that mean you're disturbed?
