Dr. Jekyll was the “good” one on the surface, while Mr. Hyde was the darker, violent side of the same person.

In Strange Case of Dr. Jekyll and Mr. Hyde , Jekyll is presented as a respectable doctor with a public reputation for decency and charity, but Hyde is the embodiment of his hidden evil impulses. The twist is that they are not really two separate people in the usual sense; Hyde is Jekyll’s altered, freer, more monstrous self.

So the simple answer is:

  • Dr. Jekyll = the good, respectable side.
  • Mr. Hyde = the bad, destructive side.
