You should read the Strange Case of Dr Jekyll and Mr Hyde as a follow up.
The original inspiration for it was Stevenson hearing about respectable pillar of Edinburgh society, William Brodie, being caught as a burglar, stealing to repay his gambling debts. Your social capital in Victorian Britain was based around your outward appearance of respectability and had to be defended to the utmost. If you were outed as a criminal, or as a homosexual, you'd lose every shred of privilege and position.
With that in mind, you can imagine the duality of Dr Jekyll trying to maintain his good standing while licentious Mr Hyde wants to engage in hijinks?
