We like to paint individuals––either in real life or in literature––as heroes or villains. Jewish wisdom teaches that we are neither good nor evil, but rather that both a yetzer hatov and a yetzer hara that exists within each and every one of us. When Dr. Henry Jekyll, in Robert Louis Stevenson’s “The Strange Case of Dr. Jekyll and Mr. Hyde,” figures out how to separate his evil inclination and his moral inclination into two separate beings, he creates a monster on the one hand, and a feeble wimp on the other. Living a purposeful and meaningful life requires that we are driven by a healthy balance between our moral and primal natures.
