Well, Jekyll and Hyde has been made a into musical (with none other than David Hasselhoff playing the lead role). Watch the opening two scenes and note the biblical echoes (e.g. "in the twinkling of an eye") about what it says about human evil and how one might go away in liberating humanity from its clutches.
So we learn that science can have a go, but in the end it does not have all the answers. How then do we defeat evil, not the evil of others, but the evil of ourselves? I'm reminded of what Paul says at the end of Romans 7.24-25: "What a wretched man I am! Who will rescue me from this body of death? Thanks be to God—through Jesus Christ our Lord!"
