Was Dr. Jekyll Real?

Was this character a Narcissist or a Psychopath - or Both? I'm not making the diagnosis here, just examining the story and it's origins.

Robert Lewis Stevenson was the creator of the classic, The Strange Case of Dr. Jekyll and Mr. Hyde. A classic horror novel that has captured the imagination of many and has been made into a motion picture several times.

It seems, along with nightmares and scientific journals, a man named Deacon Brody, was one of the inspirations for the characters Jekyll and Hyde. Brody was a distinguished and trusted gentleman of status who chose, or somehow was compelled by the demons in his own mind, to live a rather duplicitous life.

Deacon Brodie was a respected businessman, a city councilor, a cabinetmaker, and a locksmith. Who was always dressed in his finest, and who was always present at the best social events. On the surface he lived a respectable life with a wife and children – but he also lived a secret life filled with gambling, drunkenness, cockfighting, two mistresses, and 5 illegitimate children.

Narcissist, psychopath, schizophrenic, or multiple personalities - what do you think?
