Here is an existential matter to chew on at the opera: why are we women so often attracted to men who are total, utter bastards? That question has been tackled in innumerable books, films and more – classic material for mass-selling bonkbusters, the exploits of James Bond and, of course, Fifty Shades of Grey.
But the man who seduces, rapes or maltreats the women in his life – and he is usually powerful and rich– is not just a mythic archetype. He is all too real and he is here with us right here, right now. Politicians, pop stars, footballers, a president or two, even the occasional conductor – it seems they're at it left, right and centre.
As the Royal Opera House prepares to unveil a new staging of Mozart's darkest opera, Don Giovanni, its serial-seducer antihero seems almost ridiculously relevant. The fast-living aristocrat rapes Donna Anna, emotionally tortures Donna Elvira and seduces the peasant girl Zerlina on her wedding day – all this within 24 hours. His undoing begins when he is challenged by the Commendatore, Anna's father, and kills him.
The Don is sung in Kasper Holten's new production by the Polish baritone Mariusz Kwiecien. "A character like Don Giovanni could exist in every era – 500 years ago, 200 years ago, now and in the future," he says. "A certain number of people always become addicted to money, drugs, fame, partying, all these crazy things, and just lose themselves in this kind of behaviour."
That life is fatal for Don Giovanni – and it rings true: "Think of Michael Jackson, Whitney Houston, Amy Winehouse," adds Kwiecien. "It's the people who are not strong enough to say no, enough, let's stay on the brighter side of this world. The darkness always seduces people, and if you have money, power and fame it's easier to let it."
Finally, Giovanni gets a grisly comeuppance: he must face retribution from the ghost of the man he murdered in scene one. He seems to deserve his fate – yet one rarely leaves the theatre without a frisson of sympathy for the dead and damned Don. That sympathy can still be perplexing. Why on earth do we care about this man?
Perhaps the key is the opera's edgy libretto by Lorenzo Da Ponte – who some say took advice about the Don's character from Casanova himself. It allowed Mozart to create a cast of thoroughly believable individuals, none of whom is all good or all bad. For instance, the sheer chutzpah of Giovanni's twisted logic can prove oddly irresistible as he explains to his sidekick, Leporello, that to be faithful to one woman would mean being unfaithful to all the others. He also sings one of the most gorgeous arias ever given to an operatic baritone, a serenade addressed to the unfortunate Donna Elvira's maid.
Gerald Finley is one of today's most sought-after Giovannis. "I think we're always fascinated by people who are doing extraordinary things, perhaps beyond our own moral range," he comments, "and in seeing perhaps things that only feature in our dreams sometimes playing out in other people's lives. And to see this character incarnated on stage, put together by Da Ponte and Mozart, combines all those issues."
The darkness wins as the Commendatore drags Giovanni away to hell. But Kwiecien takes a pragmatic view of why we still can't help loving that man. "Good is boring," he says. "Bad is much more interesting."
